Question

The problems on slides 6 and 7 in the PPT Slides (Shown below). For these two problems assume a material, etc. and sketch the shear force and bending moment diagrams. Then solve for a suitable shaft diameter ORa factor of safety, assuming one or the other. This is for practice!) e 6 Shaft: F 2000 lbf F2 1100 lbf 3 in -3 in B T AA AC T 3300 lbf in 2421 Ibf 3300 lbf in 9 lbf e 7 Shaft: wI 35 lbf W2=55 lbf -7 in- 13 in 11 in_ 31 in
