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 :

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

          \($w=h_2 - h_1$\)

              = 116.09 - 101

              = 15.09

Therefore, \($w= 15.09 \text{ Btu/lbm}$\)

The maximum bending moment that the load has in pounds would be 2700lb.

When the shear force at that portion is zero or changes sign due to the point of contra flexure, when the bending moment is zero, the maximum bending moment occurs in the beam. Reason: Because it results in convexity downhill, the positive bending moment in a section is taken into account.

The shear force would then have to change the sign when it is at the load position.

Such that we would have

R₁ * 12

where R₁ = 225

225 x 12 = 2700

We can cross check the solution by solving for the right side

= R₂ x 12

= 675 lb x 12

= 2700 lb

Hence we would say that the maximum bending moment in pounds is 2700.

Answer:

Explanation:

In Shunt DC Motors, the speed can be controlled using the following techniques:

Armature voltage control - By varying the armature voltage, the magnetic field produced by the armature current can be controlled, which affects the speed of the motor. Thus, the speed of the motor can be regulated by controlling the armature voltage.

Field resistance control - The speed of the motor can also be controlled by varying the field resistance. By increasing the field resistance, the flux produced by the field winding is decreased, and the speed of the motor increases. Conversely, reducing the field resistance increases the flux and decreases the speed.

Armature resistance control - In this method, the resistance of the armature circuit is varied. By increasing the armature resistance, the current in the motor reduces, leading to a decrease in the speed of the motor.

In Series DC Motors, the speed can be controlled using the following techniques:

Armature voltage control - Similar to shunt motors, the speed of the series motor can be regulated by varying the armature voltage.

Field flux control - As the name suggests, the flux produced by the field winding can be controlled by varying the field winding resistance. By increasing the field resistance, the flux reduces, leading to an increase in speed. Conversely, decreasing the field resistance increases the flux and decreases the speed.

Armature resistance control - By varying the armature resistance, the current in the motor can be controlled. Increasing the resistance decreases the current, leading to an increase in speed.

Overall, these techniques enable the speed control of shunt and series DC motors, allowing them to be used in a wide range of applications where variable speed control is required.

Approximately 3,266 units must be sold each year for breakeven. This means that at this sales volume, the revenue from selling these units would be sufficient to cover both the fixed costs and the variable costs, resulting in no profit or loss.

The breakeven point is the point at which the total revenue equals the total costs, resulting in neither profit nor loss. To calculate the breakeven point in units, we divide the fixed costs by the contribution margin per unit. The contribution margin per unit is the difference between the unit selling price and the variable cost per unit.

In this case, the fixed costs are $800,000 per year. The contribution margin per unit is calculated as follows:

Contribution Margin per Unit = Unit Selling Price - Variable Cost per Unit

Contribution Margin per Unit = $2,950 - $2,705

Contribution Margin per Unit = $245

To determine the breakeven point in units, we divide the fixed costs by the contribution margin per unit:

Breakeven Point (in units) = Fixed Costs / Contribution Margin per Unit

Breakeven Point (in units) = $800,000 / $245

Breakeven Point (in units) ≈ 3,265.31

When it comes to saving money, there are several different options available to choose from depending on the amount of risk you are willing to take and the length of time for which you want to save.

Savings accounts, certificates of deposit, money market accounts, and savings bonds are some of the most common tools for saving money.Savings Account: A savings account is the most common tool for saving money. They are insured by the Federal Deposit Insurance Corporation (FDIC) and typically earn interest at a low rate. These accounts are an excellent option for short-term financial goals such as saving for a vacation, a down payment, or a rainy day fund.Certificate of Deposit (CD): Certificate of deposit (CD) is a savings account with a fixed term and interest rate. A CD is typically insured by the FDIC, and the interest rate is usually higher than a savings account.

CDs are an excellent option for medium-term financial goals such as saving for a new car, a home renovation, or education.Money Market Account (MMA): A money market account (MMA) is similar to a savings account, but it typically offers a higher interest rate. However, these accounts have a minimum deposit requirement and may require a higher balance to avoid fees. Money market accounts are a good option for medium-term financial goals such as saving for a down payment on a home or for a child's college education.Savings Bonds: Savings bonds are issued by the U.S. Treasury and are backed by the full faith and credit of the U.S. government.

Both A and B are correct. Front-wheel drive cars frequently have press-fit cartridge-style wheel bearings installed in the knuckles.

On many cars, both the front and the rear wheel bearings are typically sealed inside bolt-on hub assemblies. Uneven weight distribution over the contact patch may result from underinflated tires starting to lose their correct form. Both tread edges may begin to deteriorate noticeably more quickly than other parts of the tire if they are subjected to increased weight. The wheelset's dynamic unbalance will increase, increasing the lateral force, derailment coefficient, and wheel unloading ratio as well as decreasing the hunting critical speed and the quality of the vertical ride. Dynamic imbalance can also be brought on by a damaged tire or wheel, however it typically results from manufacturing variances. Dynamic imbalance, of course, degrades ride quality and tends to hasten the deterioration of tire and steering and suspension system parts.

Calculate The minimum fiber volume fraction using the relation below

E = x * E1 + ( 1 - x ) E2  ------ ( 1 )

given that :

E = 83 GPa , x = ?

E1 = 260 GPa ,  E2 = 2.4 GPA

Insert values back into equation 1

Then ; 80.6 = 257.6 x

The values of h at the two internal boundaries are :

Given data :

Z₁ = Z₂ = Z₃ = 25 m

h top = 120 m

h bottom = 100 m

K₁ = 0.0001 m/s

K₂ = 0.0005 m/s

K₃ = 0.0010 m/s

we will apply the formula below since flow is perpendicular to the bedding plane

Keq = \(\frac{Z1 + Z2 + Z3 }{\frac{Z1}{K1}+\frac{Z2}{K2} + \frac{Z3}{K3} }\)  ----- ( 1 )

Insert values given above into equation 1

Therefore ; Keq = 2.307 * 10⁻⁴ m/s

Hydraulic gradient ( Ieq ) = head loss / length

                                          = ( 120 - 100 ) / 3 * 25

                                   Ieq  = 0.266

Given that the flow is perpendicular to bedding plane

q1 = q2 = q3

V₁ = V₂ = V₃ = V

K₁i₁ = K₂i₂ = K₃i₃ = Keq * ieq

Hence :

V = Keq* Ieq

   = 2.307 * 10⁻⁴ * 0.266

   = 6.15 * 10⁻⁵ m/s .

Also;

K₁i₁ =  Keq * ieq = K₂i₂ = K₃i₃

therefore :

  i₁ = 0.615

  i₂ =  0.123

  i₃ = 0.0615

Pressure at point 1 ( i.e. pressure between first two formations )

h₁ = h top - i₁L₁

   = 120 - 0.615 * 25

   = 104.625 m

Pressure at point 2 ( i.e. pressure between the 2nd and 3rd formation )

h₂ = h₁ - i₂L₂

    = 104.625 - 0.123 * 25

    = 101.55 m

μ = 0.2, R = 14 inches, N = 150 rpm

For the maximum possible draft in one pass,

\($\Delta h = H_0-h_f=\mu^2R$\)

     \($=0.2^2 \times 14 = 0.56$\) inches

\($h_f = 2.2 - 0.56$\)
