1. Figure Q1 shows a load bearing structural member of a machine. It is attached to a fixed support at the top and subjected to an axial tensile load of P. The thickness of the member t = 20 mm. It is made from AISI 1030 plain carbon steel and the machine is operated in room-ambient environment. The estimated stress concentration factors at the hole at A and the fillet at B are 2.20 and 1.70 respectively. Estimate the permissible axial load P that can be safely applied on the structural member. State all your selections and assumptions clearly. You may refer to the data tables available in appendix to extract appropriate data. = TA 20 mm rB = 15 mm 64 mm 88 mm B Figure Q1 P (20 marks)
