- A 20-mm-diameter steel [E = 194 GPa; a = 11.6 x 10-6/°C] bolt is used to connect two rigid parts of an assembly, as shown in the figure. The bolt length is a = 160 mm. The nut is hand-tightened until it is just snug (meaning that there is no slack in the assembly, but there is no axial force in the bolt) at a temperature of T- 42°C. When the temperature drops to T--5°C, determine (a) the clamping force that the bolt exerts on the rigid parts (positive if in tension and negative if in compression).

A steel bolt through a 25-in long aluminum tube has the nut turned on until it just touches the end of the tube. No stress is introduced on the bolt or the tube. The temperature of the assembly is raised from 70 to 79 degrees Fahrenheit. The cross-sectional area of the bolt is 0.08 sq. inch and the cross-sectional area of the tube of 0.25 sq. inch. For steel: E = 30 x 10^6 psi, coefficient of thermal expansion = 6.5 x 10^-6 per degree Fahrenheit. For aluminum: E = 10 x 10^6 psi, coefficient of thermal expansion = 13.0 x 10^-6 per degree Fahrenheit. Find the thermal deformation (in inches) of the steel bolt.
