The post is made from 6061-t6 aluminum and has a diameter of 50 mm. it is fixed supported at a and b, and at its center c there is a coiled spring attached to the rigid collar. 0.25 m 0.25 m k = 200 mn/m > b part a if the spring is originally uncompressed, determine the compression in the spring when the load of p = 70 kn is applied to the collar. express your answer to three significant figures and include appropriate units. hår o 2 ? opp = .129 mm submit previous answers request answer x incorrect; try again; 5 attempts remaining

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.
