Answer:

IV > \(I^{2} R\)

Explanation:

The current in the power line = I

The voltage in the power line = V

The resistance of the power line = R

Power supplied from the power house = P

power delivered to the households = \(p\)

We know that the power supplied to a power line system is proportional to

P = IV    ....1

we also know that according to Ohm's law, the relationship between the voltage, resistance, and current through an electrical system is given as

V = IR    ....2

substituting equation 2 into equation 1, the power delivered to the households is proportional to the square of the current.

\(p\) = \(I^{2} R\)    ....3

The problem is that when power is delivered across a transmission line, some of the power is loss due to Joules heating effect of the power lines. This energy and power loss is proportional to \(I^{2}\) therefore, the electrical power delivered to the households will be less than the electrical power supplied from the power station. This means that

P > \(p\)

equating these two powers from equations 1 and equation 3, we have

IV > \(I^{2} R\)

Answer:

To calculate M2, p2, and T2 at the exit of the combustor, we can use the isentropic relations for a nozzle, assuming that the flow through the combustor is adiabatic and isentropic.

Using the isentropic relations, we can relate the Mach number, pressure, and temperature at the exit of the combustor to their values at the inlet of the combustor.

M2 = sqrt((2/(gamma-1))*((T1/(1+((gamma-1)/2)*M1^2))*(1+((gamma-1)/2)*M1^2*0.5*(gamma+1)*0.5*(1+0.5*(gamma-1)*M1^2)^(-1)*(1-0.5*(gamma-1)*M1^2*0.5*(gamma+1)*0.5*(1+0.5*(gamma-1)*M1^2)^(-1)*(1+0.5*(gamma-1)*M1^2*0.5*(gamma+1)*0.5*(1+0.5*(gamma-1)*M1^2)^(-1)*((gamma+1)/(2*gamma))^((gamma+1)/(2*(gamma-1))))))^(-1))

where gamma = 1.4 is the specific heat ratio of the fuel-air mixture.

Substituting the given values, we get:

M2 = sqrt((2/(1.4-1))*((570/(1+((1.4-1)/2)*0.4^2))*(1+((1.4-1)/2)*0.4^2*0.5*(1+0.5*(1.4-1)*0.4^2)^(-1)*(1-0.5*(1.4-1)*0.4^2*0.5*(1+0.5*(1.4-1)*0.4^2)^(-1)*(1+0.5*(1.4-1)*0.4^2*0.5*(1+0.5*(1.4-1)*0.4^2)^(-1)*((1.4+1)/(2*1.4))^((1.4+1)/(2*(1.4-1))))))^(-1)) = 0.818

p2 = p1*(1+0.5*(gamma

Explanation:

One might expect that the cost of owning a vehicle would not be a function of its color. There is no reason to believe that a blue car gets better gas mileage than a green car of the same make, model, and equipment. So, the appropriate choice is ...

  a. vehicle color

__

However, vehicle color may play a role in ownership costs if more money is spent on washing a white car than would be spent on a black or beige car. Similarly, a light-colored car may require less use of an air-conditioner in the summer sun than does a dark-colored car, ultimately affecting fuel cost. It isn't always obvious what the features of a vehicle are that contribute to ownership cost.

answer ;

voltage drop in the Vcd branch = 30 V

Voltage drop in the middle branch = 40v - 30v = 10 volts

voltage drop in AB = 60 + ( -600 * 0.05 ) = 60 - 30 = 30 volts

Explanation:

Determine voltage drop from top terminal to bottom terminal ( Vab ) in the right hand branch and Vcd in left hand branch

40v and 50mA are in series hence;  Ix = 50mA

also Vcd = 30V

CD is parallel to AB hence; Vcd = Vab = 30 V

Vab = ∝*Ix + 60 v

 30v  = ∝ ( 50mA ) + 60

therefore ∝ = -600

voltage drop in the Vcd branch = 30 V

Voltage drop in the middle branch = 40v - 30v = 10 volts

voltage drop in AB = 60 + ( -600 * 0.05 ) = 60 - 30 = 30 volts

The aggregation of project safety allows the project team to reduce overall safety to a value that is less than the sum of individual task safeties by considering the interactions and dependencies among various tasks and safety measures.

When evaluating project safety, it is important to recognize that the safety of individual tasks or components alone does not necessarily guarantee overall project safety. The aggregation of project safety involves analyzing the interactions and dependencies among different tasks, processes, and safety measures to identify potential risks and vulnerabilities that may arise when these elements interact. By considering the interdependencies, the project team can identify opportunities to optimize safety measures and reduce overall safety risks. This approach allows for a more holistic perspective on safety, where synergies and efficiencies can be leveraged to enhance overall safety performance. It is through this aggregation and consideration of the project as a whole that the team can identify and implement measures to reduce overall safety risks to a level that may be less than the sum of individual task safeties.

Explanation:

yun anserr hhehehe

Given, Failure time (in hours) of a pressure switch is log-normally distributed with parameters

μt = 4 and σt = 0.9. (9 pts)

MTTF for the pressure switch= E(T) where T is the life of the product. From the data, we have; Mean, μt = 4 and Standard deviation, σt = 0.9.Using the relationship between lognormal and normal distribution i.e If X~ Lognormal

(μ,σ^2) then Y=ln(X)~

Normal(μ,σ^2), we can find the value of

MTTF;Y=ln(X) ln(MTTF)= μ = 4 and σ^2=0.9^2=0.81

Hence, Y~N(4, 0.81)So, E(T)=exp(μ+σ^2/2)=exp

(4+0.81/2) =exp(4.405)= 81.85

Thus, MTTF for the pressure switch = 81.85 hours. When should the pressure switch be replaced, if the minimum required reliability is 0.95?Given, Minimum required reliability = 0.95.It is required to find when the reliability of the switch falls below the minimum requirement. Let R(T) be the reliability function of the switch. Then,

R(T) =P(T > t)

where T is the life of the switch.

R(T)= P(T > t)= P(log T > log t)= P [(log T - μ)/σ > (log t - μ)/σ]= 1 - Φ [(log t - μ)/σ]

can be found by solving the above equation as follows;

0.95= R(t) = 1 - Φ [(log t - μ)/σ]Φ [(log t - μ)/σ]= 0.05

using standard normal tables, we get

Φ(1.64)= 0.95approx (log t - μ)/σ= 1.64log t= μ + σ

(1.64)log t= 4+0.9(1.64)= 5.476t= antilog (5.476)= 239.42

So, the switch should be replaced after 239.42 hours. The hazard function for the time computed in part b is given by h(t)=f(t)/R(t)where f(t) is the probability density function of T (the life of the product) and R(t) is the reliability function of the product. Thus, the value of h(t) at 239.42 hours is;

h(239.42)= f(t)/R(t)= 0.0005074/0.05= 0.01014

The value of the hazard function for the time computed in b is 0.01014.

Explanation:

The forces in truss members AB, BC, and AC are:

AB = 5kN

BC = 7.07kN

AC = 2kN

The length of truss AC is (0.8m + 0.6m) = 1.4m

The distance of truss AC to point B (or the vertex created by A and C) is 0.8m

To solve for the forces in members AB, BC, and AC, we can use the method of joints. Starting with joint B:

The force in member AB is 5kN (given)

The force in member BC can be calculated using the equilibrium equation ΣFx = 0:

BC*cos(45) = AB

BC = AB/cos(45)

BC = 5kN/0.7071

BC = 7.07kN

The force in member AC can be calculated using the equilibrium equation ΣFy = 0:

ACsin(45) + BCsin(45) = P

ACsin(45) + 7.07sin(45) = 8

AC = (8 - 7.07)/sin(45)

AC = 1.42/sin(45)

AC = 2kN

The fastest way to fasten wood together is to use pneumatic nailers or nail guns.

Pneumatic nailers, also known as nail guns, are power tools that use compressed air to drive nails into wood quickly and efficiently. They are designed to make the process of fastening wood much faster compared to traditional methods such as using hammers and nails.

Pneumatic nailers work by loading nails into a magazine or a strip, which is then fed into the tool. When the trigger is pulled, the compressed air drives a piston or hammer mechanism, which forcefully pushes the nail into the wood, securing the pieces together.

The speed and ease of use offered by pneumatic nailers make them ideal for tasks that require a large number of fasteners or repetitive nailing, such as framing, carpentry, and construction projects. They can save significant time and effort compared to manual nailing, allowing for increased productivity and efficiency.

It's important to note that proper safety precautions should be followed when using pneumatic nailers, including wearing protective eyewear and following the manufacturer's guidelines for safe operation.

When it comes to fastening wood together quickly, pneumatic nailers or nail guns are the fastest option.
