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.
