In the gear system shown in Figure P6.31/32, the motor applies a torque of 600 N-m to the gear at A. Shafts (1) and (2) are solid shafts, and the bearings shown allow free rotation of the shafts.

(a) Determine the torque T_E
provided by the gear system at gear E.

(b) If the allowable shear stress in each shaft must be limited to 70 MPa, determine the minimum permissible diameter for each shaft.
