Tech A says that a gear set that has a drive gear with 9 teeth and a driven gear with 27 teeth has a gear ratio of 3:1. Tech B says that the drive gear is also called the output gear. Who is correct?

Answers

Answer:

Tech A is correct.

Explanation:

Gears are toothed wheels that can be used to transmit power. When two or more gears are in tandem, a gear train is formed.

Gear ratio = \(\frac{number of teeth of the driven gear}{Number of teeth of the driving gear}\)

                = \(\frac{27}{9}\)

                = \(\frac{3}{1}\)

Gear ratio = 3:1

The driver gear is called the input gear since it transfers its power to the driven gear. While the driven gear is called the output gear because it produces an effect due to both gears.

Tech A is correct.

  7.2×10^-6/°F for structural steel

Then the difference in expansion dimensions for a 42-inch length will be ...

  (42 in)((7.2 -5.8)×10^-6/°F)(165 -60)°F = (42 in)(1.4×10^-6)(105) = 0.006174 in

The difference in thermal expansion over that temperature range will be about 0.006174 inches.

of surface area is twice as great for the for the hemisphere as it is for the cylindrical side wall. Determine the dimensions to be used if the volume is fixed and the cost of construction is to be kept to a minimum. Neglect the thickness of the silo and waste in construction.​

Answers

An extremum is a point where the function has its highest or lowest value, and at which the slope is zero.

The dimensions to be used if the volume is fixed and the cost of construction is to be kept to a minimum is as follows;

Height of cylinder = 2 × Radius of cylinder

Reason:

The given parameters are;

Form of silo = Cylinder surmounted by a hemisphere

Cost of construction of hemisphere per square unit = 2 × The cost of of construction of the cylindrical side wall

Required:

The dimensions to be used if the volume is fixed and the cost of construction is to be kept to a minimum

Solution:

The fixed volume of the silo, V, can be expressed as follows;

\(V = \pi \cdot r^2 \cdot h + \dfrac{2}{3} \cdot \pi \cdot r^3\)

\(h = \dfrac{V - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 }\)

Where;

h = The height of the cylinder

r = The radius of the cylinder

The surface area is, Surface Area = 2·π·r·h + 2·π·r²

The cost, C = 2·π·r·h + 2×2·π·r² = 2·π·r·h + 4·π·r²

Therefore;

\(C = 2 \times \pi \times r\times \dfrac{V - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 } + 4 \cdot \pi \cdot r^2 = \dfrac{8 \cdot r^3 \cdot \pi + 6 \cdot V}{3 \cdot r}\)

\(C = \dfrac{8 \cdot r^3 \cdot \pi + 6 \cdot V}{3 \cdot r}\)

At the minimum value, we have;

\(\dfrac{dC}{dr} =0 = \dfrac{d}{dr} \left(\dfrac{8 \cdot r^3 \cdot \pi + 6 \cdot V}{3 \cdot r} \right) = \dfrac{16 \cdot r^3 \cdot \pi - 6 \cdot V}{3 \cdot r^2}\)

Which gives;

16·π·r³ = 6·V

\(V = \dfrac{16 \cdot \pi \cdot r^3}{6} = \dfrac{8 \cdot \pi \cdot r^3}{3}\)

Which gives;

\(h = \dfrac{\dfrac{8 \cdot \pi \cdot r^3}{3} - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 } = 2 \cdot r\)

h = 2·r

The height of the silo, h = 2 × The radius, 2

Therefore, the dimensions to be used if the volume is fixed and the cost is to be kept to a minimum is, height, h = 2 times the radius

Key term of Bimetal strip

Answer:

Bimetallic strip is a strip consisting of two metals of different coefficients of expansion welded together so that it buckles on heating : used in thermostats.

the properly exposed radiograph was obtained for an aluminum weld 3 in thick with the source 60 in. from the film. the geometric unsharpness, however, was found to be unsatisfactory and source-to film distance was increased to 120 in. what would be a proper exposure time for this new placement, compared to the original exposure time t 0 ?

Answers

When the source-to-film distance was increased from 60 in. to 120 in., the geometric unsharpness was improved. This means that the image on the radiograph will be sharper and clearer, making it easier to identify any defects or issues with the weld.

However, the increased distance will also result in a decrease in radiation intensity, which will affect the exposure time required to obtain a properly exposed radiograph.To determine the proper exposure time for the new placement, we can use the inverse square law. This law states that the intensity of radiation is inversely proportional to the square of the distance from the source.So, if the original exposure time was t0, and the distance was doubled to 120 in., the new exposure time would need to be increased by a factor of 4 (2 squared) to maintain the same radiation intensity at the film.Therefore, the proper exposure time for the new placement would be 4 times the original exposure time, or 4t0.The proper exposure time for the new placement would need to be increased to compensate for the decrease in radiation intensity due to the increased source-to-film distance. Using the inverse square law, we can determine that the new exposure time should be 4 times the original exposure time.

Here is the solution to the problem you have posted:Define a function repeats of type 'a list -> bool so that repeats (L) is true if and only if the list L has two equal elements next to each other using pattern matching.

Let's consider the pattern matching method to define the function repeats.Let's consider the function repeats and the argument 'a list L of the function repeats. We will define the repeats function with the help of pattern matching. We have two cases here, the first is when L is an empty list, and the second is when L has at least one element. Here's how the function can be defined:def repeats(L) = match L with | [] -> false | x::xs -> let rec helper(a,b) = match b with [] -> false | y::ys -> if a=y then true else helper(y, ys) in helper(x,xs)The function repeats is defined recursively with the help of the helper function.

The helper function is defined inside the repeats function with two arguments, a and b. The purpose of the helper function is to traverse the list L and check whether there are any two adjacent elements that are equal. If there are two such elements, it will return true; otherwise, it will return false.

If a first order system's characteristic value, 8, is smaller than zero, we may say that it is dynamically stable. Rolling convergence is the term used to describe the motion, which is a damped roll rate.

Explain the aircraft dynamic modes ?Two parameters can be used to define oscillating motions: the duration of one full oscillation and the duration needed to damp to half-amplitude, or the duration needed to double the amplitude for a dynamically unstable motion. A long-period oscillation known as a phugoid mode and a short-period oscillation known as the short-period mode make up the two different oscillations that make up the longitudinal motion.The "phugoid mode," which has a longer period, is characterised by large amplitude variations in air speed, pitch angle, and altitude but almost no variations in angle of attack.As the aircraft tries to return to the equilibrium level-flight condition from which it had been disturbed, the phugoid oscillation is a slow exchange of kinetic energy (velocity) and potential energy (height) around some equilibrium energy level.

In using semaphores to control access to a critical section, we initialize the semaphore’s counter to 1. What happens if we initialize it to 0? to 2?

Answers

Semaphores are used to control access to a shared resource, such as a critical section, in a concurrent system. The semaphore maintains a counter that represents the number of available resources.

When a process requests access to the shared resource, it must acquire the semaphore, decrement the counter, and release the semaphore when it is done with the resource. This ensures that only one process can access the critical section at a time, preventing race conditions and other synchronization issues.

If we initialize the semaphore's counter to 0, it means that there are no resources available. Any process that tries to acquire the semaphore will block until another process releases the semaphore and increments the counter. This can be useful in cases where we want to ensure that a process waits for a resource to become available before proceeding.

A 13 kg rock sits on a spring with a spring constant of 23,000 N/m. The spring has a natural length of 1.2 meters.
a. If the spring is oriented horizontally, how much must the spring be compressed so that the rock will be traveling at 35 mph when it leaves contact with the spring?
b. If the spring is oriented vertically, how high will the rock get above the ground if the spring is compressed by 0.5 meters before the rock is released from a resting position?
c. If the rock is dropped vertically onto the spring (with the bottom of the spring on the ground) from a height of 14 meters above ground, how far will the spring compress before the rock stops moving? This is harder than it first appears and you should end up solving a quadratic equation.

Answers

a. To find the compression of the spring needed to launch the rock horizontally at 35 mph, we can use conservation of energy. The potential energy stored in the compressed spring is equal to the kinetic energy of the rock when it leaves the spring:

1/2 k x^2 = 1/2 m v^2

where k is the spring constant, x is the compression distance, m is the mass of the rock, and v is the velocity of the rock.

Converting the velocity to meters per second:

35 mph = 15.6 m/s

Plugging in the values and solving for x:

1/2 (23,000 N/m) x^2 = 1/2 (13 kg) (15.6 m/s)^2

x = sqrt[(13 kg) (15.6 m/s)^2 / (23,000 N/m)] = 0.263 m

Therefore, the spring must be compressed by 0.263 meters.

How high will the rock get above the ground if the spring is compressed by 0.5 meters before the rock is released from a resting position?

b. To find the maximum height the rock will reach when the spring is oriented vertically, we can again use conservation of energy. The potential energy stored in the compressed spring is converted into gravitational potential energy of the rock when it leaves the spring:

1/2 k x^2 = m g h

where g is the acceleration due to gravity and h is the maximum height reached by the rock.

Plugging in the values and solving for h:

1/2 (23,000 N/m) (0.5 m)^2 = (13 kg) (9.8 m/s^2) h

h = (1/2) (23,000 N/m) (0.5 m)^2 / (13 kg) (9.8 m/s^2) = 0.605 m

Therefore, the rock will reach a height of 0.605 meters above the ground.

c. To find the compression distance when the rock is dropped onto the spring from a height of 14 meters, we need to consider both the potential energy of the rock and the energy absorbed by the spring. When the rock hits the spring, it will come to a stop, so all of its initial potential energy will be converted into potential energy stored in the compressed spring:

m g h = 1/2 k x^2

where h is the initial height of the rock and x is the compression distance of the spring.

Plugging in the values and solving for x, we get a quadratic equation:

1/2 (23,000 N/m) x^2 - (13 kg) (9.8 m/s^2) (14 m) = 0

Simplifying and solving for x using the quadratic formula:

x = sqrt[(13 kg) (9.8 m/s^2) (14 m) / (23,000 N/m)] = 0.473 m

Therefore, the spring will compress by 0.473 meters before the rock comes to a stop.

h = (1/2) (23,000 N/m) (0.5 m)^2 / (13 kg) (9.8 m/s^2) = 0.605 m

Therefore, the rock will reach a height of 0.605 meters above the ground.

c. To find the compression distance when the rock is dropped onto the spring from a height of 14 meters, we need to consider both the potential energy of the rock and the energy absorbed by the spring. When the rock hits the spring, it will come to a stop, so all of its initial potential energy will be converted into potential energy stored in the compressed spring:

m g h = 1/2 k x^2

where h is the initial height of the rock and x is the compression distance of the spring.

Plugging in the values and solving for x, we get a quadratic equation:

1/2 (23,000 N/m) x^2 - (13 kg) (9.8 m/s^2) (14 m) = 0

Simplifying and solving for x using the quadratic formula:

x = sqrt[(13 kg) (9.8 m/s^2) (14 m) / (23,000 N/m)] = 0.473 m

Therefore, the spring will compress by 0.473 meters before the rock comes to a stop.

A vehicle battery is consistently low on voltage. Technician A says to disconnect the battery with the engine running to test for proper alternator output. Technician B says that a loose alternator belt may cause this problem. Who is right

Answers

A vehicle battery is consistently low on voltage, a loose alternator belt may cause this problem. In this case, Technician B is right.

A loose alternator belt can cause the alternator to not charge the battery properly, leading to a consistently low voltage. Disconnecting the battery with the engine running, as suggested by Technician A, is not recommended as it can cause damage to the electrical system and does not provide an accurate assessment of the alternator's performance. Instead, it's better to use a multimeter to test the alternator output.

Disconnecting the battery while the engine is running can lead to voltage spikes and other electrical issues that may harm sensitive electronic components. It is generally advised to avoid this practice.

Describe a project in which you would use a pleater, ruffling foot, or gathering foot. Explain each of these tools and choose the one that might be necessary for the project you are describing.(FASHION DESIGN)

Answers

A project that requires using a pleater, a ruffling foot, or a gathering foot is the creation of a dress.

A pleater, a ruffling foot, and a gathering foot are all accessories for sewing machines or machines themselves that help fashion designers to give the fabric a different shape or texture, and therefore create unique pieces.

Pleater: This tool includes multiple needles that go through the fabric to create multiple pleatsRuffling foot: This is usually an accessory for sewing machines to create rufflesGathering foot: This tool is used to create gathers in fabric, these differ from ruffles because they are smaller and more subtle than ruffles

All of the tools can be used in the creation of a dress, for example, a pleater can be used in the top section of the dress to give it a nice texture and make it different from the skirt. In the same way, others such as the ruffling foot or the gathering foot can be used in the sleeves of the dress.
