Mathematics · Thermal Stress
A circular bar is rigidly fixed at both ends, where the bar uniformly tapers from a diameter of 50 mm at one end to 30 mm at the other end. If the temperature is raised by 30 K, find the maximum stress developed in the bar. Take Young's modulus E = 120 GPa and the coefficient of thermal expansion α = 6 × 10 -6 /K.
