Question:
A brass tie bar of length 700mm and diameter 30mm undergoes a change in temperature from 40 degree celsuis to 130 degree celsuis. the linear expansivity of copper is 19 x 10^-6 C^-1 and the modulus of elasticity is 86 GPa.
determine the change of length that takes place
Determine the compressive force induced in the bar if it is rigidly held and expansion is prevented.
