Question

In the system shown in Figure P6.20, the motor applies a
torque TA = 40 N ⋅ m to the pulley at A. Through a sequence of pulleys
and belts, this torque is amplified to drive a gear at E. The
pulleys have diameters DA = 50 mm, DB = 150 mm, DC = 50 mm,
and DD = 250 mm.
(a) Calculate the torque TE that is produced at gear E.
(b) Shaft (2) is to be a solid shaft, and the maximum shear stress
must be limited to 60 MPa. What is the minimum diameter
that may be used for shaft (2)?
