3. 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 × 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.

Transcribed Image Text:3. 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. (Write your answer to
6-decimal places. ) *
