In a borrow pit, the natural soil was found to have a moist unit weight of 112 pcf. The insitu water content is 12.0%, and the specific gravity of soil solids is 2.7. The geotechnical engineer has decided to excavate, haul, and compact this soil in a highway embankment fill to a dry unit weight of 115 pcf at an optimum water content of 15%. If 10,000 cubic yard of compacted fill are required:
a. How many cubic yards of borrow material are required to be excavated?
b. If the compacted fill later becomes saturated by heavy rainfall, without change in the compacted void ratio: Compute the saturated water content and saturated unit weight.

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
