Problem 16 Calculate the DMS angle between these two bearings (two solutions): Bearing 1 = S 66° 11' 55" W and Bearing 2 = S 66° 11' 55" E

A 100 ft steel tape standardized at 68 °F and supported throughout under a tension of 10 Ibs was found to be 100.2 ft long. The tape had a cross sectional area of 0.009 in? and a weight of 0.03 Ib/ft. The tape is used to measure a horizontal distance (AB) and the measured length comes out to be 300 ft. CALTRANS plans a new ramp to connect Nutwood with US57. The ramp starts from point A (on Nutwood) to C (on US57) wherein point C will be vertically above point B (a current point on Nutwood that will get buried by ramp). The must have a smooth 4% grade, thus the tape will be used fully supported. Determine the correct slope distance to be measured (i.e. length AC) if a pull of 15 Ibs is used and the temperature is 96 °F.

9.5 Calculate the north azimuth for sides OA, OB, OC, andOD in the accompanying figure.

12. The garage doors are on the south side of the building. Which detail shows the foundation under the garage doors? What is unusual about the detail?

2.26 A driver traveling down a 4% grade collides with a roadside object in rainy conditions, and is issued a ticket for driving too fast for conditions.The posted speed limit is 65 mi/h. The accident investigation team determined the following: The vehicle was traveling 40 mi/h when it struck the object, braking skid marks started 205 ft before the struck object, the pavement is in good condition, and the braking efficiency of the vehicle was 93%. Using theoretical stopping distance, assuming aerodynamic resistance is negligible, and with the coefficient rolling resistance approximated as 0.015, should the driver appeal the ticket? Why or why not?

3.11 Repeat Problem 3.10 if the tape is 0.030 in. thick and3/8 in. wide.(Ans.: 3.83 Ibs)

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).

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?

Question 3 (20 points): Forte Composites Inc would like to invest in upgrading polymer concrete products fabrication in its Virginia plant. Three mutually exclusive design options are being considered.All have a 10-year useful life. If the MARR is 22%, determine which design should be selected based on:a) the PW method, b) AW method, and c) the IRR method. (Note: perform incremental analysis only for the IRR method)
