The expression for the current in the form i(t) = im*cos(ωt+θ) is: i(t) = 28.28*cos(2π x 1000 t + 0.942) A

To write the expression for the given sinusoidal current i(t) in the form i(t) = im*cos(ωt+θ), we need to determine the amplitude im, the angular frequency ω, and the phase angle θ.

The given current has an rms value of 20A, which means that the amplitude of the current is:

im = √2 * Irms = √2 * 20A = 28.28A (approx.)

The period of the current is 1ms, which corresponds to a frequency of:

f = 1 / T = 1 / (1ms) = 1 kHz

The angular frequency is:

ω = 2πf = 2π * 1 kHz = 2π x 1000 rad/s

The current reaches a positive peak at t = 0.3ms, which corresponds to a phase angle of:

θ = ωt - π/2 = (2π x 1000 rad/s) x (0.3 x 10^-3 s) - π/2 ≈ 0.942 radians

Therefore, the expression for the current in the form i(t) = im*cos(ωt+θ) is:

i(t) = 28.28*cos(2π x 1000 t + 0.942) A

Yes, one pound-force is the force required to accelerate a mass of 32.174 lbm by 9.807 ft/s2.

This is the gravitational acceleration at sea level, which is the acceleration due to gravity. This means that a mass of 1 lbm will weigh 1 lbf if it is placed at sea level.

The force of gravity is the result of an attractive force between two objects, which is proportional to the mass of both objects and inversely proportional to the square of the distance between them. This means that the greater the mass of an object, the greater the force of gravity it will experience.

Therefore, the mass of 1 lbm will experience a force of gravity of 1 lbf when placed at sea level. This is why the weight of an object is typically measured in units of pounds.

The landfill has a volume of 16.2ha * 10m = 162,000m³.

Each week, 765m³ of waste is dumped, which is compacted to half its volume, so 382.5m³ is added weekly.

Annually, this amounts to 382.5m³/week * 52 weeks = 19,890m³/year.

With a total volume of 162,000m³ and an annual addition of 19,890m³, the expected life of the landfill can be estimated by dividing the total volume by the annual addition: 162,000m³ / 19,890m³/year ≈ 8.14 years.

It is proved from the below that the temperature of the egg varies from the shell to the center of the egg.

Using the 2-dimensional finite element method, we will need to find the Biot number of the system by using the formula:

\(\mathbf{Bi = \dfrac{h_c r_o}{k} }\)

According to the Heisler chart, the curves in the graph represent a range of values for the inverse of the Biot number,

where;

\(\mathbf{Bi = \dfrac{h_c r_o}{k} }\)

here;

By developing nodes based on assumptions;

\(\mathbf{Bi = \dfrac{1700 \times 0.025}{0.682} }\)

Bi = 62.32

The inverse of Biot number is:

\(\mathbf{=\dfrac{1}{Bi}}\)

\(\mathbf{=\dfrac{1}{62.32}}\)

= 0.016

Similarly, the Fourier number \(\mathbf{F_o}}\) is calculated by using the expression;

\(\mathbf{F_o = \dfrac{\alpha t }{r_o^2} }\)

\(\mathbf{F_o = \dfrac{k t }{\rho c_pr_o^2} }\)

where;

\(\mathbf{F_o = \dfrac{0.682 \times 15 \times 60 }{958.4 \times 4211 \times 0.025^2} }\)

\(\mathbf{F_o = 0.243}\)

Using the 2-dimensional finite element method, the temperature ratio is:

\(\mathbf{\dfrac{T(0,t) -T_{\infty}}{T_o -T_{\infty}} = 0.1 }\)

T(0,t) = 100 + 0.1(4-100)

T(0,t) = 100 + 0.1(-96)

T(0,t) = 100 - 9.6

T(0, t) = 90.4° C

The initial enthalpy and the entropy of the saturated water can be found out from the table of A-12E

i.e.   \($h_1= 101 \ \text{Btu/lbm}$\)

       \($s_1 = 0.22717 \text{ Btu/lbmR}$\)

Since the process mentioned above is an adiabatic compression process, the entropy will remain constant throughout the process. Therefore, we take the value of entropy and the final pressure using the table with few interpolations and also approximations to find the final enthalpy. It is given by :

       \($h_2= 116.09 \text{ Btu/lbm}$\)

So the work input from the energy balance equation :

       \($\dot{W} + \dot{m}h_1 = \dot{m}h_2$\)

          \($w=h_2 - h_1$\)

If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

We need to perform a two step process to obtain the maximum shear stress on the shaft. For the solid shaft,

P=2×pi×N×T/60 or T=60×p/2×pi×N

Where P=power transmitted by the shaft=50×10³W

N=rotation speed of the shaft in rpm=730rpm

Pi=3.142

T is the twisting moment

By substituting the values for pi, N and P, we get

T=654Nm or 654×10³Nmm

Also, T=pi×rho×d³/16 or rho=16×T/pi×d³

Where rho=maximum shear stress

T = twisting moment=654×10³Nmm

d= diameter of shaft= 40mm

By substituting T, pi and d

Rho=52Mpa

b. For a hollow shaft, the value for rho is unknown

T=pi×rho(do⁴-di⁴/do)/16

Rho=T×16×do/pi×(do⁴-di⁴)

Where

T= twisting moment=654×10³Nmm gotten above

do=outside shaft diawter=40mm

di= inside shaft diameter =30mm

Pi=3.142

Substituting values for pi, do, di and T.

Rho=76Mpa

Therefore, If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

Engineers work in teams to design and implement various products using specific processes. The correct option is A.

An engineer is a person who designs, builds, and maintains machinery and structures like bridges, railroads, and highways using scientific knowledge.

The word engineer, from which the term engineering is derived, was first used in 1390 to refer to "a constructor of military engines." The term engine'er literally means "one who operates an engine."

In this now-outdated meaning, the term "engine" refers to a military machine, or a mechanical device employed in battle.

An engineer is someone who practices engineering, and those who are qualified to do so may hold more official titles like "Designated Engineering Representative," "Professional Engineer," "Chartered Engineer," "Incorporated Engineer," "Ingenieur," or "European Engineer."

Teams of engineers design and deploy various goods utilizing predetermined procedures.

Answer:

Explanation:

Step one:

given data

V1=0.25m^3

T1=290k

P1=100kPa

V2=0.5m^2

T2=405k

P2=? final pressure

Step two:

The combined gas equation is given as

P1V1/T1=P2V2/T2

Substituting we have

(100*0.25)/290=P2*0.05/405

25/290=0.5P2/405

0.086=0.05P2/405

cross multiply

0.086*405=0.05P2

34.9=0.05P2

divide both sides by 0.05

P2=34.9/0.05

P2=698.3Kpa

Therefore the new pressure is 698.3Kpa when the gas is compressed

Here's a function called Close Enough which takes a const reference to a vector of strings and an int. This function is used to check if there are two adjacent strings in a list that are very similar to each other by determining the number of characters that can be different between any two strings next to each other.

The function starts by iterating through the vector of strings from the first to the second to last string. For each string, it then counts the number of differences between it and the next string by comparing the characters at each position.

If the number of differences is less than or equal to the given integer n, the function returns the index of the current string. If there is no such index, the function returns -1.

The steel used for light guage steel framing differs from steel discussed in steel frame construction chapter in that light guage steel is cold-rolled.

In essence, cold rolled steel is hot rolled steel that has undergone annealing or temper rolling after being allowed to cool at room temperature. Compared to hot rolling, cold rolling creates steel with tighter dimensional tolerances and a larger range of surface treatments. Through the use of strength hardening, it is additionally up to 20% stronger than hot rolled.

Steel that has been cold rolled often has a better, more polished surface and tighter tolerances. Additionally, it produces shinier, oilier surfaces. Additional benefits include:

The statement given "From the producers, the energy flows to the consumers (primary consumers, secondary consumers, tertiary consumers.) Then the energy exits the ecosystem when an organism dies, and the energy is passed to decomposers." is false because energy does not exit the ecosystem when an organism dies.

Instead, when an organism dies, the energy contained in its body is transferred to decomposers, such as bacteria and fungi, through the process of decomposition. Decomposers break down the organic matter of dead organisms and release the stored energy back into the ecosystem in the form of nutrients. These nutrients can then be taken up by producers (plants) through nutrient cycling, restarting the flow of energy through the ecosystem. This process ensures that the energy remains within the ecosystem and is continually recycled rather than exiting the system.
