In the figure shown, shaft OA, made of AISI 1030 hot-rolled steel, is welded to a fix support at 0 and subjected to loading by forces F1, F2, F, and the external moment Me as shown below. The shaft has a20 mm. Any possible deformation of the shaft will take place along the x-axis only, and diameter d axial stresses are neglected. Stresses are to be considered at support O. The forces are F120 N, F230 N, and F350 N, and Me= 10 N.m. 1. Find the moment(s) and torque(s) that each force will produce on the shaft at O [4.5 Marks] 2. Find the resultant moment and resultant torque at O [4 Marks 3. Find the bending and shear stresses at O [3 Marks] 4. Find the factor of safety for shaft OA by using the Maximum Shear Stress theory and specify whether the structure is safe or not 3.5 Marks]
