Question

The aluminum rod AD (E=73 GPa, 0=23x10°6/°C) has a diameter of 15 mm and is
attached to the rigid support at A when the temperature T; = 30°C. If the
temperature becomes T: = -20°C, and the axial loads are applied to the rod as
shown, determine:

a) The location and magnitude of the maximum stress acting on the rod AD
b) Displacement of point D
c) Average strain in part BC

The aluminum rod AD (E=73 GPa, a=23×10-6/°C) has a diameter of 15 mm and is
attached to the rigid support at A when the temperature T1 = 30°C. If the
temperature becomes T2 = -20°C, and the axial loads are applied to the rod as
shown, determine:
a) The location and magnitude of the maximum stress acting on the rod AD
b) Displacement of point D
c) Average strain in part BC
