A reinforced masonry beam is designed to resist a given bending moment, using the allowable stress design method. If the effective depth is halved, while width and reinforcement are kept constant, the effect will be (A) to halve the maximum compressive stress in the masonry (B) insignificant (C) to double the maximum compression stress in the masonry (D) to quadruple the maximum compressive stress in the masonry

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

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.
