Two circular polycarbonate [E = 7.6 GPa; ν = 0.36; α = 29 ×10-6/°C] disks are shown. At an initial temperature of Ti = 23°C, the diameter of the smaller disk is D = 90 mm and the thickness of the disk is t = 8.1 mm. At a final temperature of Tf = 53°C, determine the thickness of the disk.

A rigid steel bar is supported by three rods as shown. There is no strain in the rods before the load P is applied. After load P is applied, the normal strain in rods (1) is 2,740 μm/m. Assume initial rod lengths of L1 = 1,250 mm and L2 = 2,000 mm. Determine the normal strain in rod (2).

Two circular polycarbonate [E = 7.6 GPa; ν = 0.36; α = 29 ×10-6/°C] disks are shown. At an initial temperature of Ti = 15°C, the diameter of the smaller disk is D = 80 mm and the thickness of the disk is t = 8.9 mm. At a final temperature of Tf = 52°C, determine the thickness of the disk.
