6. (30 points) Special Problem. BM Zulu has an elevation of 310.36 ft. You wish to establish the elevation of a new benchmark to be known as BM Boracho. A vertical control survey was completed. Use the sketch below to complete the field notes, as follows: a) Compute all elevations, b) Complete the arithmetic check, c) Determine the error of closure, d) If the error is acceptable, adjust the elevations. Assumptions: The distances between points are equal. Allowable error (mm) = 2*(No. of Turning Point)0.5

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.
