Chapter 2.13, Problem 101P
The cylindrical rod AB has a length L = 5 ft and a 0.75-in. diameter; it is made of a mild steel that is assumed to be elastoplastic with E= 29 × 106 psi and σY = 36 ksi. A force P is applied to the bar and then removed to give it a permanent set δp. Determine the maximum value of the force P and the maximum amount δm by which the bar should be stretched if the desired value of δp is (a) 0.1 in., (b) 0.2 in.

required to drive the machine varies in a cyclic manner over a period of 2 revolutions. The torque drops
from 20,000 Nm to 10,000 Nm uniformly during 90 degrees and remains constant for the following 180
degrees. It then rises uniformly to 35,000 Nm during the next 225 degrees and after that it drops to
20,000 in a uniform manner for 225 degrees, the cycle being repeated thereafter.
Determine the power required to drive the machine and percentage fluctuation in speed, if the driving
torque applied to the shaft is constant and the mass of the flywheel is 12 tonnes with radius of gyration of
500 mm. What is the maximum angular acceleration of the flywheel.
