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.

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
