Also, the modulus of elasticity E is 6.0 GPa, and the coefficient of thermal expansion is 100 x10%C°. The bar is subjected to a uniform temperature increase of 30°C.Calculate the following quantities: (a) the compressive force P in the bar. (b) the maximum compressive stress sc. (c) the displacement of point C.
