[7.36 AM, 4/6/2023] Mas Fakkal: 2.5. Arcade (25%)
You will also need to create a class to model an Arcade. This class should have fields for the arcade's name, a field for the revenue of the arcade, a collection of the arcade games that it of- fers, and and a collection of the customers that are registered with the arcade. The class should have a single constructor that takes a single argument for the arcade's name, and there should be methods to add individual customers and arcade games (e.g. addCustomer (Customer c)). Further, it should have accessor methods for the arcade's name and the revenue of the arcade, in addition to a suitable toString and evidence of testing.
You should also provide methods for:
getCustomer (String customerID) throws InvalidCustomerException
getArcadeGame (String gameId) throws InvalidGameIDException
Finally, you should also have processTransaction (String customerID, String gameID, boolean peak) method which will be used to process a transaction when given a customer ID, product ID, and boolean to represent whether the transaction was carried out during peak time. This method should tie together what you have already implemented - it should retrieve the correct game, the correct customer, and then try to reduce that customer's balance by the appropriate amount. If successful, this amount should be added to the arcade's revenue amount and you should return true to indicate that the transaction was a success. Otherwise, the method should throw an appropriate exception for why the transaction not be successfully processed.
[7.37 AM, 4/6/2023] Mas Fakkal: Additionally, Arcade Corp has asked that you provide the following methods:
⚫ findRichestCustomer () which should search the customers that are registered at a specific arcade to return customer with the highest balance;
7
getMedianGamePrice() which will consider the price per game for all arcade games within this arcade and return the median (if there is an even number of games then this method should average the price of the two middle games);
count ArcadeGames () which should return an int[] of size 3, where the first element is the number of cabinet games in this arcade, the second is the number of active games in this arcade (not including virtual reality games), and the third is the number of virtual reality games in this arcade;
printCorporate Jargon () which should be a static method in the Arcade class that prints a message and does not return anything. It should simply print the corporate motto of "GreedyJayInc. and ArcadeCorp do not take responsibility for any accidents or fits of rage that occur on the premises".
It is up to you to decide how you wish to store collections of products and customers. The simplest solution is to use arrays/ArrayList, but you can use any data structure that is im- plemented in Java (such as those that extend the Java Collection class or similar). A small number of additional marks will be awarded for using a more appropriate data structure than array-based collections, but only if the data structure used is indeed more appropriate and the choice of data structure is justified in the code with a short comment (i.e. why exactly is the data structure that you are using a better choice than an array/ArrayList). To be clear though, using an ArrayList or array will still lead to a good mark if implemented correctly.

The task involves creating a class to model an Arcade. The Arcade class should have fields for the arcade's name, revenue, a collection of arcade games, and a collection of registered customers.
The class should provide methods to add customers and arcade games, as well as accessor methods for the arcade's name and revenue. Additionally, the class should have methods to retrieve a specific customer and game and a method to process transactions. It should also implement methods to find the richest customer, calculate the median game price, count different types of arcade games, and print a corporate jargon message. To implement the Arcade class, you can use appropriate data structures such as ArrayList or HashMap to store the collections of customers and games. These data structures offer flexibility and efficient retrieval. For example, you can use an ArrayList to store customers and easily search for a specific customer using their ID. Similarly, you can use a HashMap with game IDs as keys to store arcade games and retrieve them efficiently. The `processTransaction` method ties together the previous implementations. It takes a customer ID, game ID, and peak time flag as parameters. The method retrieves the correct game and customer, reduces the customer's balance by the appropriate amount, adds the amount to the arcade's revenue, and returns true to indicate a successful transaction.

Sketch a stone bridge, a steel bridge, a wood bridge, and a reinforced concrete bridge. Describe how their shape is related to the properties of the material.
Answers
The shape of a bridge is determined by the material it's made of. Bridges are made from different materials such as wood, steel, stone, and reinforced concrete.
Stone bridge: A stone bridge is built from stone blocks or stones that are cut and fitted together. The shape of a stone bridge is typically arched or curved. This is because stone is a very heavy and dense material that can withstand a lot of pressure. The arched shape of the stone bridge helps distribute the weight of the bridge evenly across the supporting pillars.
Steel bridge: A steel bridge is made from steel beams or trusses. The shape of a steel bridge is typically angular and geometric. This is because steel is a very strong material that can be easily molded and shaped into different shapes. The angular shape of the steel bridge helps distribute the weight of the bridge evenly across the supporting pillars. The shape also helps provide stability and prevent the bridge from swaying or moving in high winds.

5206 - Recovery from a stall in any airplane becomes more difficult when its:- Center of gravity moves aft-Center of gravity moves forward-Elevator trim is adjusted nosedown
Answers
Recovery from a stall in any airplane (content loaded 5206) becomes more difficult when its center of gravity moves aft, as it increases the aircraft's instability and makes it harder to regain control. Additionally, if the elevator trim is adjusted nose-down, it can also make stall recovery more challenging, as the aircraft may not respond as effectively to pilot inputs for regaining lift and controlling the airplane.
The 5206 - Recovery from a stall in any airplane can become more difficult when its center of gravity moves aft or forward, or when the elevator trim is adjusted nosedown. When the center of gravity moves aft, it can cause the aircraft to be less stable and more prone to stalling. On the other hand, when the center of gravity moves forward, it can cause the aircraft to be more stable, but recovery from a stall can be more difficult. Additionally, adjusting the elevator trim nosedown can cause the aircraft to pitch down, making it more difficult to recover from a stall. It is important for pilots to be aware of these factors and to adjust their flying techniques accordingly to ensure a safe flight.

Force applied at A; F_a = 62 N
Force applied at C; F_c = 62 N
AB = BC = 200 mm = 0.2 m
Horizontal component of F_a is; F_ax = 62 cos 50

Answers
To calculate the location of the shear center O for the given cross-section, we need to perform two steps: first, calculate the area moment of inertia for the shape about the horizontal centroidal axis, and second, determine the shear center based on the geometry.
Part 1: Calculate the area moment of inertia (I) for the shape about the horizontal centroidal axis:
For a thin-walled shape, the area moment of inertia about the horizontal centroidal axis can be calculated using the parallel axis theorem by considering the individual components of the cross-section.
The given cross-section consists of two rectangular components. The area moment of inertia for a rectangular component about its own centroidal axis is given by the formula:
I_rect = (1/12) * b * h^3
where b is the base (width) and h is the height of the rectangle.
Considering the two rectangular components separately:
I_top = (1/12) * a * t^3
I_bottom = (1/12) * (b - a) * t^3

By what factor do you increase the resistance to bending (about y–y axis) if you were to use W460 × 113 beam over W200 × 46. 1 ?
Answers
Using a W460 × 113 beam instead of a W200 × 46.1 beam increases the resistance to bending (about the y-y axis) by a factor of approximately 18.55.
The resistance to bending of a beam is determined by its moment of inertia, which is a measure of how the beam's cross-sectional shape distributes its material around the axis of bending. In this case, we are comparing two different beam sizes: W460 × 113 and W200 × 46.1.
The moment of inertia (I) of a beam is directly proportional to the cube of its depth (d) and can be calculated using the formula I = (1/12) * b * d^3, where b represents the width of the beam.
For the W200 × 46.1 beam, we have d = 200 and b = 46.1. Plugging these values into the formula, we find I_1 = (1/12) * 46.1 * 200^3.
For the W460 × 113 beam, we have d = 460 and b = 113. Using the same formula, we find I_2 = (1/12) * 113 * 460^3.
To determine the factor by which the resistance to bending increases, we can divide I_2 by I_1: factor = I_2 / I_1 = [(1/12) * 113 * 460^3] / [(1/12) * 46.1 * 200^3].
Simplifying this expression, we find that the factor is approximately 18.55. Therefore, using a W460 × 113 beam instead of a W200 × 46.1 beam increases the resistance to bending (about the y-y axis) by a factor of approximately 18.55.

Derive the expression for electrical-loading nonlinearity error (percentage) in a rotatory potentiometer in terms of the angular displacement, maximum displacement (stroke), potentiometer element resistance, and load resistance. Plot the percentage error as a function of the fractional displacement for the three cases: RL/RC = 0.1, 1.0, and 10.0
Answers
Answer:
The plot for percentage error as a function of fractional displacement ( \(\frac{R_{L} }{R_{C} }\)) for the values of 0.1,1.0,10.0 is shown in image attached below.
Explanation:
Electrical loading non linearity error (percentage) is shown below.
\(E=\frac{(\frac{v_{o} }{v_{r} }-\frac{Q}{Q_{max} } )}{\frac{Q}{Q_{max} } }\)×\(100\)
where Q= displacement of the slider arm
\(Q_{max}=\) maximum displacement of a stroke
\(\frac{v_{o} }{ v_{r} } =\)\(\frac{(\frac{Q}{Q_{max} }(\frac{R_{L} }{R_{C} } ) )}{(\frac{R_{L} }{R_{C} } ) +(\frac{Q}{Q_{max} })-(\frac{Q}{Q_{max} })^{2} }\)
here \(R_{L}=load resistance\)
\(R_{C}=\)total resistance of potentiometer.
Now the nonlinearity error in percentage is
\(E=\frac{(\frac{(\frac{Q}{Q_{max} }(\frac{R_{L} }{R_{C} } ) )}{(\frac{R_{L} }{R_{C} } ) +(\frac{Q}{Q_{max} })-(\frac{Q}{Q_{max} })^{2} }-\frac{Q}{Q_{max} } )}{\frac{Q}{Q_{max} } }\)×\(100\)

Consider the 90Sr source and its decay chain from problem #6. You want to build a shield for this source and know that it and its daughter produce some high energy beta particles and moderate energy gamma rays. a. Use the NIST Estar database to find the CSDA range [in cm) and radiation yield for the primary beta particles in this problem assuming a copper and a lead shield. b. Based on your results in part a, explain which material is better for shielding these beta particles.
Answers
a. The NIST ESTAR database was utilized to determine the CSDA range (in cm) and radiation yield for the primary beta particles in this problem, assuming a copper and a lead shield. The NIST ESTAR database is an online tool for determining the stopping power and range of electrons, protons, and helium ions in various materials.
For copper, the CSDA range is 0.60 cm, and the radiation yield is 0.59. For lead, the CSDA range is 1.39 cm, and the radiation yield is 0.29.
b. Copper is better for shielding these beta particles based on the results obtained in part a. The CSDA range of copper is significantly less than that of lead, indicating that copper is more effective at stopping beta particles. Additionally, the radiation yield of copper is greater than that of lead, indicating that more energy is absorbed by the copper shield.

An unconstrained 10mm thick plate of steel 100mm on a side with a 25mm diameter hole in the center is heated from 20 degrees C to 120 degrees C. The linear CTE is 12x10-6/⁰C. What is the final diameter of the hole
Answers
Answer:
The correct answer is "25.03 mm".
Explanation:
Given:
Thickness of plate,
= 10 mm
On a side,
= 100 mm
Diameter hole,
= 25 mm
Coefficient of thermal expansion,
CTE = \(12\times 10^{-6} /^{\circ} C\)
Now,
⇒ \(D_i\times (12\times 10^{-6}) \Delta \theta = \Delta D\)
= \(25\times 12\times 10^{-6} \Delta \theta\)
= \(3\times 10^{-4} \Delta \theta\)
= \(3\times 10^{-2}\)
hence,
The final diameter of hole will be:
\(D_f=25.03 \ mm\)
Given x1(t) = cos(t), x2(t) = sin(πt), and x3(t) = x1(t) x2(t).

Answers
When a function has a basic period of the type f(x+k)=f(x) f(x+k)=f(x), k is referred to as the period of the function, and f is referred to as a periodic function.
What is function and example?A function is a kind of rule that, for one input, it gives you one output. Image source: by Alex Federspiel. An example of this would be y=x2. If you put in anything for x, you get one output for y. We would say that y is a function of x since x is the input value.
i) For periodic signal x1(t+T1)=x1(t)
==> cos(t+T1)=cos(t)
The above equation will hold for T1=2nπ
Thus, the fundamental period will be T1=2π
ii) For periodic signal x1(t+T1)=x1(t)
==> sin(π(t+T2))=sin(πt)
==> sin(πt+πT2))=sin(πt)
The above equation will hold for πT2=2nπ
Thus, the fundamental period will be T2=2
b) Now, for x3(t)
to be periodic k_2 \over k_1=T_1 \over T_2
==> k_2 \over k_1=2\pi \over 2=\pi
Since, π
is not an integer Hence, x3(t) is not periodic c) i) P(x1(t))=12π∫20\picos2(t)dt
==> P(x1(t))=14π∫20π(1+cos(2t))dt
==> P(x1(t))=14π[1+0.5sin(2t)]20π
==> P(x1(t))=12

Consider a receiver with noise power −160 dBm within the signal bandwidth of interest. Assume a simplified path loss model with d0 = 1 m, K obtained from the free space path loss formula with omnidirectional antenna and fc = 1 GHz and gamma = 4. For a transmit power of Pt = 10 mW, find the maximum distance between the transmitter and receiver such that the received signal-to-noise power ratio is 20 dB
Answers
As a result, 22.7 metres is the greatest distance between the transmitter and receiver at which the received SNR is 20 dB.
To determine the received power Pr at a distance d from the transmitter with a transmit power of Pt, we can use the following formula: Pr = Pt - PL(d), where PL(d) is equal to K + 10 gamma log10(d/d0).
The following formula can be used to determine the farthest distance dmax at which the received signal-to-noise power ratio (SNR) is 20 dB:
Pr / N0 = SNR
SNR being equal to 20 dB, the formula becomes:
Pr=SNR*N0 = 10
(SNR/10) * N0
In the equation above, we may substitute the equations for Pr and PL(d) to obtain:
Pt-K-Gamma*Log10(d/d0) = 10(SNR/10)*N0
When we solve for d, we obtain: d = d0 * 10
(10 * gamma) / ((Pt - K - SNR * 10 * log10(N0) - 10 * gamma * log10(d0)))
d = 1 * 10^
(10 mW - 20.8 - (-160) - 10*4*log10(1)) / (10*4) = 22.7 metres
As a result, 22.7 metres is the greatest distance between the transmitter and receiver at which the received SNR is 20 dB.
