Two tape spools are attached to an axle supported by bearings at A and D . The radius of spool B is 1.5 in. and the radius of spool C is 2 in. Knowing that TB= 20 lb and that the system rotates at a constant rate, draw the free-body diagram needed to determine the reactions at A and D . Assume that the bearing at A does not exert any axial thrust and neglect the weights of the spools and axle.
A 20-kg ladder used to reach high shelves in a storeroom is supported by two flanged wheels A and B mounted on a rail and by a flangeless wheel C resting against a rail fixed to the wall. An 80-kg man stands on the ladder and leans to the right. The line of action of the combined weight W of the man and ladder intersects the floor at point D. Determine the reactions at A, B, and C.
Two 9-in.-diameter pipes (pipe 1 and pipe 2) are supported every 7.5 ft by a small frame like that shown. Knowing that the combined weight of each pipe and its contents is 30 lb/ft and assuming frictionless surfaces, determine the components of the reactions at A and G.
