An industrial equipment manufacturing factory needs a 1.5m long shaft that can deliver 75kW @ 600rpm. The design concept will consider factor of safety of 2.5. Both solid & hollow shafts are considered. For hollow shaft, outside-to-inside diameter ratio is 6:5. Material considerations are as tabulated: Solid shaft Hollow shaft 240MPA 3.5° 83GPA 7,200kg/m³ | 7,200kg/m³ P82./kg Properties |Max. torsional strength Max. angular deflection Modulus of rigidity Material density Material cost 200MPA 2.5° 83GPA P135./kg Compute the most economic design of shaft which conforms to customer's requirement.

Part A For a hard aluminum notched part having notch dimension r = 0.75 in, geometric stress-concentration factor Kt = 2.8, material strength Sut = 50 kpsi, and bending loading type, find the Neuber factor, a (in inches). Part B Find the material's notch sensitivity, q. Part C Find the fatigue stress-concentration factor. Kf.

A solid shaft 15 meters long is stressed to 85 MPa when twisted through 6 degrees. If G = 83 GPa. What power in kW can be transmitted at 1000 rpm?
