Blocks d and f weigh 5 lb each and block e weighs 8 lb. the cord connecting the blocks passes over small frictionless pulleys. determine the sag s for equilibrium. the frame shown is subjected to three coplanar forces. replace this loading with a single resultant force and specify, the distance from a, where the resultant's line of action intersects member ab. determine the magnitudes of f 1 and f 2 and the direction of f 1 so that the loading creates a zero resultant force and couple on the wheel. the radius of the wheel is 0.75 ft.

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.
