For the beam shown, determine a. All reactions at the fixed end of the cantilever. Draw proper free body diagrams. b. If the cross-section is a circle of radius 1 inch, sketch the cross-section at the fixed end of the shaft, and determine the maximum bending stress only, and specify where it occurs on the cross-section. c. Sketch the state of maximum bending stress on a volume element taken from the location on the cross-section where the maximum bending stress occurs. 2 kip/ft 6 ft -3 ft 4 kip 20 kip-ft
