Question
4. An alloy circular bar rigidly fixed at its both ends uniformly tapers from 90 mm to 60 mm from one end to another. What will be the maximum stress developed in the bar, when its temperature is raised through 20 K? Take E and a for the bar material as 150 GPa and 12 x 10 /K. Also find the maximum stress when the bar is lowered by the same temperature. [Ans. 54 MPa (Compn.): 54 MPa (Tension)]
