A 13-kN hydraulic press for removing and reinstalling bearings in small-to medium-sized electric motors is to consist of a commercially available cylinder mounted vertically in a C- frame, with dimensions as sketched in the Figure shown below. It is being proposed to use ASTM A-48 (Class 50) gray cast iron (brittle material with ultimate strength, Su= 345 M P a) for the C-frame material. Calculate the maximum bending tensile stress in M P a?

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
