Repeat Problem 2.18 where the motor develops a torque of 200 lb-in. during operation.
Problem 2.18
The motor shown operates at constant speed and develops a torque of 100 lb-in. during normal operation. Attached to the motor shaft is a gear reducer of ratio 5:1, i.e., the reducer output shaft rotates in the same direction as the motor but at one-fifth motor speed. Rotation of the reducer housing is prevented by the "torque arm," pin-connected at each end as shown in Figure P2.18. The reducer output shaft drives the load through a flexible coupling. Neglecting gravity and friction, what loads are applied to (
a) the torque arm,
(b) the motor output shaft, and
(c) the reducer output shaft?
