A rectangular steel alloy A-36 (structural steel) plate is hanging vertically and supporting a hanging weight of 90 kN. The plate has a length of 0.5 m, a width of 75 mm, and a thickness of 6 mm. If the YS = 250 MPa and the UTS = 450 MPa: a.) What is the maximum load that the bar can withstand without fracturing? b.) What is the max design load that you would specify (ignore safety factors)?
