7075-T6 Al has a tensile yield strength of σY=450 MPa. A circular tube of 7075-T6 Al supports an axial load of 60 kN in tension and a torque of 1.0 kN-m. The average diameter of the tube is 50.0 mm. Use the von Mises yield criterion.(a)What is the safety factor against yielding if the wall thickness is 2.0 mm? (1.5)(b)What value of thickness with the same diameter would provide a safety factor of 2.0 against yielding? (2.6 mm)

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
