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?
Transients on an open line. A lossless open transmission line is given as shown in Figure 16.41. The line is 10 m long and has a capacitance of 200 pF/m and inductance of 0.5 μH/m. Calculate the transient voltage at a distance of 5 m from the dc s..
