Question 87
XE-DNAT2 marksNeeds review
A bar of length L = 1 m is fixed at one end. Before heating its free end has a gap of δ = 0.1 mm from a rigid wall as shown in the figure. Now the bar is heated resulting in a uniform temperature rise of 10 °C. The coefficient of linear thermal expansion of the material is 20 × 10⁻⁶ /°C and the Young’s modulus of elasticity is 100 GPa. Assume that the material properties do not change with temperature. The magnitude of the resulting axial stress on the bar is ____ MPa (in integer).
