3.18 tis desired to determine the height of a church steeple.Assuming that the ground is level, a 350.00-ft length is to measured out from the base of the steeple and a 40°15vertical angle is determined from that point on the ground to the top of the steeple. How tall is the steeple?

The average monthly inflow into a reservoir in a dry year is given in Table 3. If a uniform discharge of 90 c f s is desired from this reservoir, what minimum storage capacity is required ?

The main structural members holding up the roof are TS columns and W beams. What sheet shows where they go and details the specific member size?

3. You wish to develop a 12.5 acres plot of land. The area is basically a square. a. What is the area in square feet? b. In square meters? c. If a standard city lot is about 8600 square feet, how many lots can be cut from your area(discounting the area for streets and utilities).

17. In the space below, draw the approximate location of a 195° azimuth and a S45E bearing.

Problem 1: Given the following vertical curve data: PVI at 19 + 00; L = 500 ft; g1 = +2.5 percent; g2 = -1 percent; elevation at PVI = 723.86 ft, compute the elevations of the curve summit (high point) and even full stations (i.e., 100-ft even stations).

13-10A highway project is expected to cost $1,700,000 initially. The annual operating and maintenance cost after the first year is $5000 and will increase by $500 each year for a project lifespan of 20 years. At the end of the tenth year, the project must be resurfacedat a cost of $300,000. (a) Calculate the present worth of costs for this project over a 20-year period if the annual interest rate is 5 percent. (b) Convert the value obtained in (a) to equivalent uniform annual costs.
