A copper cylinder 150mm outside diameter has walls 25mm thick. End plates are stayed by a 25mm diameter bar of steel which passes through the cylinder and is just tight at -11°C. Estimate the stress in cylinder and stay when steam at atmospheric atmosphere (100°C) is admitted. Assume the end plates do not deform.

222. two decimal places
A copper cylinder 150mm outside diameter has walls 25mm thick. End plates are stayed
by a 25mm diameter bar of steel which passes through the cylinder and is just tight at
-11°C. Estimate the stress in cylinder and stay when steam at atmospheric atmosphere
(100°C) is admitted. Assume the end plates do not deform.
Use the following values:
ac = 17 x 10-6/°C
Ec = 117 GPa
a, = 12 x 10-6/°C
Es = 200 GPa
