Calculate the maximum Dead Load Deflection, Live Load Deflection and Long Term Deflection for the simply supported beam below. The dead load including its own weight is 1 k/ft. The live load is 0.7 k/ft. Assume 30% sustained live load for 3 years and a 20 ft span. Use 3000 psi normal weight concrete and 60,000 psi steel.

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.
