Answer to Question #76024 in Mechanics | Relativity for GBSM

Question

A rigidly fixed strut in a refrigeration system carries a compressive load of 50 KN when
assembled at a temperature of 20 degree Celsius. The initial length of the strut is 1.25 m
and its diameter is 30 mm. Determine the initial stress in the strut and the amount of
compression load and the factor of safety if the ultimate compressive stress of the material
is 350 MPa. Take E=150 GN/sq-m and α (Alpha) = 16 X 10 -6 /°C.
