Aship of 9,000 tons displacement floats at a draft of 23 feet and has an upper deck 34 feet above the keel. a sea breaking over the bulwarks floods a portion of the upper deck with water to a depth of 3 feet. the flooded area is 60 feet long and 40 feet wide. if kg before taking on water was 20.0 feet, calculate the reduction in gm, assuming that km remains constant. the effects of both the added weight and free surface must be determined.

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.
