To increase load carrying capacity of a tube (ID: 40mm, OD: 45mm) it was determined in the last minute that it should be reinforced by combining it with a larger tube (ID: 45mm, OD: 50mm) through shrink fitting. Measurement after machining indicated the OD of the inner tube to be 45.012 mm and ID of the outer tube to be 44.950mm. A) Find the maximum torque the assembled tube can carry. B) After assembling, if the composite tube is subjected to a bending moment of 0.675 kN*m and a torque of 0.9 kN*m, find the factor of safety in both tubes using the Distortion Energy Theory. Assume SYT to be 415 MPa.
