n earthwork contract requires to cut and move excavated rocks. The site is a typical limestone rock formation in a cut section, which is 15,000 ft long, 85 ft wide, and 3 ft deep. Seismographic tests indicate a seismic wave velocity of 5,000 fps for the rock layer material. The contractor proposes to rip the rock with a 370-hp crawler tractor. Answer the following questions.
As a Construction Manager for this site development project, prepare detailed cost estimate for the project, and bid documents.
Assume 10% time value cost of money, bonds, insurance, and storage over total direct cost, contingency at 2% of total direct cost, indirect overhead cost at 5% of total direct cost (additional on top of the equipment and operator costs), and 10% fee (on subtotal total of direct and indirect cost).

A) Refer to the diagram on “Speed Control of a Shunt Wound DC Motor.
Suppose the no load voltage V = 90V, Ra + R1 = 4 ohms, Rsh + RF = 130 ohms, and the motor runs at a rated speed of 1000 RPM when IL = 4 amps. What is the back EMF VB in volts when the motor runs at IL = 6 amps?
Note: Type a 1-decimal number, rounded off to the nearest 0.1
B) How do you know that the compound motor provides good speed control at the no-load condition?
1) The torque speed curve is flat near zero torque. This means that small changes in load do not appreciably change the speed.
2) The torque speed curve is flat near zero torque. This means that large changes in load do not appreciably change the speed.
3) The torque speed curve has a large slope near zero torque. This means that large changes in load lead to very small changes in speed.
4) The compound motor runs at slow speeds when heavily loaded.
5) Items (1) and (4)
C) You are designing a new emergency brake mechanism for an automobile featuring one of the following DC motors. Which one would you choose?
1) Permanent magnet motor
2) Brushless motor
3) Servomotor
4) Compound wound motor
5) Torque motor
(D) Suppose you are building a machine where the timing sequence of two drive axes requires that they operate at precisely the same speed. What type of motor would you select: AC or DC and why?
1) You select identical DC motors because controlling frequency input gives simple and precise speed control
2) You select identical AC motors because highly accurate and reliable AC speed controllers can be bought for very cheap prices
3) You select identical DC motors because controlling voltage input gives simple and precise speed control
4) You select identical AC motors because the variance of torque and speed specs on NEMA specified motors is very small
5) It doesn’t matter whether you select an AC or a DC motor. The cost of supplying accurate speed control for either type of motor is the same.

Explain the effect that this tax has on the firm’s fixed cost, marginal cost, average variable cost and average total cost? b. Next assume that the firm is charged a tax proportional to the number of units it produces. How does this tax affect the firm’s fixed cost, marginal cost, average variable cost and average total cost? Explain.

Required:
1. Record the inventory, purchases, and cost of merchandise sold data in a perpetual inventory record similar to the one illustrated in Exhibit 3, using the first-in, first-out method. Under FIFO, if units are in inventory at two different costs, enter the units with the LOWER unit cost first in the Cost of Goods Sold Unit Cost column and in the Inventory Unit Cost column.
2. Determine the total sales and the total cost of goods sold for the period. Journalize the entries in the sales and cost of goods sold accounts. Assume that all sales were on account.

The average total cost is at its minimum when the quantity each firm produces (q) equals 10.
Which of the following represents the equation for each firm's supply curve in the short run?
A: q
In the long run, the firm will remain in the market and produce if q is greater or equal to 10.
Currently, there are 16 firms in the market.
In the short run, in which the number of firms is fixed, the equilibrium price is $___ and the total quantity produced in the market is ___ units. Each firm produces ___ units. (Hint: Total supply in the market equals the number of firms times the quantity supplied by each firm.)
In this equilibrium, each firm makes a profit of $___. (Note: Enter a negative number if the firm is incurring a loss.)
Firms have an incentive to ___ the market.
In the long run, with free entry and exit, the equilibrium price is $___, and the total quantity produced in the market is ___ units. There are ___ firms in the market, with each firm producing ___ units.
