A solid steel box, length 0.126 m and weight 8550 N, is resting on a small deck supported by two simple supports, also separated by a length of 0.126 m. The cross section of the deck is a circle of diameter 9.45 cm. Assuming the box is a perfect rectangular prism, which length exactly straddles the length of the deck, what is the maximum normal compressive stress (Pa) in the beam (deck)

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.
