Condition #1:E A structural support for a machine is subjected to a static compression load of 20 kN. The support is manufactured from a circular rod made from SAE 1040 Hot Rolled steel. Specify suitable diameter for the cross section of the rod based on the basic size. Steel data are available in Table A-10 from the textbook. Condition #2: The same structural support of the basic size determined in Condition 1 is subjected to a tensile load of 15 kN that is repeated several thousand times over the life of the machine. This load is not an addition to the 20 kN. Specify a suitable steel that is suitable to this application based on the basic size determined in Condition #1. Loading of Condition #1 does not apply here. Condition #3: The same structural support from Condition 2 is heated from room temperature of 25°C. The support is placed inside a frame on both ends. There is a total clearance of 0.2 mm between the support and its frame. Initial length of the rod is 200 mm. Specify the…
