Learning Goal: To become familiar with and apply the concepts of maximum sustainable torque and power to solid and hollow circular shafts. A solid circular shaft and a tubular shaft, both with the same outer radius of c=co = 13.0 mm, are being considered for a particular design. The tubular shaft has an inner radius of ci = 8.00 mm. The shafts are to be powered by a motor operating at a frequency of f = 3.00 Hz and are to handle an attached load. Assume the cross-sections are uniform throughout the lengths of the shafts and that the materials have allowable shear stress of τallow = 96.0 MPa. PART A: Determine the maximum sustainable torque that the solid shaft can handle. PART B: Determine the maximum sustainable torque that the tubular shaft can handle. PART C: Determine the maximum sustainable power that the solid circular shaft can handle without failing. PART D: Determine the maximum sustainable power that the tubular circular shaft can handle without failing.
