Differntial Leveling between BM's A,B,C,D, and A gives elevation differences (in meters) of -15.632, 32.458, 38.214, and -55.025, and distances in km of 4.0, 6.0, 5.0, and 3.0 respectively.
Long Line: the slope distance and zenith angle measured from point a to point b were 17,685.20 ftand 93degrees 13' 46" . The instrument and reflector heights were equal. If the elevation of the poin
ABC is a triangular tract of land. The 1.5 tract DEFG is to be subdivided. AE is 480ft and DC is 350 ft. Determine the lengths of DG and CB. (Note 1 acre= 43,560 f^2)
The cost for maufacturing a component used in intelligent interface converters was $23000 the first year. The company expects the cost to increase by 2% each year. Calculate the presence worth over
1. A block of moist soil weighs 12.72 lbs, is 0.1050 ft3 in volume, has a water content of 9.5%, and has a specific gravity of soil solids of 2.7. Assess: Va, Vw, Vs, S, e, gama d. 2. The moist unit
Due to an error, the length L shown was 1.795 m instead of 1.80 m, thus there is a gap of 0.5 cm, which makes it difficult to bolt the bar on the structure. The engineer suggests the bar is heated u
A large rock became visible to a driver at a distance of 175 ft. Assuming a perception-reaction time of 0.8s, an initial speed of 42 mph, a coefficient of friction equal to 0.5, and a level roadway,
A car collided with a telephone pole and left 20 ft skid marks on the dry pavement. Based on the damages sustained, an engineer estimated that the speed at collision was 15 mph. If the roadway had a
The driver of a car traveling up a 2% grade at an initial speed Vo applied the brakes abruptly and the vehicles slid to a complete stop at an average deceleration of 8 ft/s^2. Was the pavement wet o
