Use your values of the elastic modulus and Poisson's ratio (experimental values) to calculate the fractional change in volume experienced by the gage section of your specimen on being stressed from zero to the maximum applied stress.

elastic modulus =29370000 psi
poison ratio =.27

original dimensions were 24.5 inches length by 1.506inches width by .4383inches height.

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.
