A simply supported beam is loaded by a couple M as shown. The beam is 2m long and of square cross section 50 mm on a side. If the maximum permissible deflection in the beam is 5mm, and the allowable stress is 150 MPa, find the maximum allowable load M. Use E=200GPa.

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.

In general, how do thermosetting plastics compare to thermoplastics in mechanical and physical properties?
