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.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
