Engineering Mechanics: Statics, Fourth Edition Pytel / Kiusalaas In Class Exercise 3.14 The shaft-and-pulley assembly ABCD is driven by the 32-lb - ft torque |(couple) supplied by the electric motor at A. The assembly is also subjected to the two belt tensions shown at each of the two pulleys. Determine the force-couple system at D that is equivalent to the torque and the four belt tensions. Solution: 26 lb 12 lb -1.0 ft Move all the forces to 12 point D. Write the forces in 12 lb 26 lb 32 lb · ft -0.75 ft 8 lb vector form. Sum all forces to obtain Pulley C 32 lb resultant force R at D. 8 lb 1.5 ft For each force on each 32 lb pulley, draw their position vectors from point D: On pulley C, identify the required position 8 lb TDE ГDF 32 lb y D vectors
