Condition 3 step by step Condition #1:A structural support for a machine is subjected to a static compression load of 20 kN. The support ismanufactured from a circular rod made from SAE 1040 Hot Rolled steel. Specify suitable diameter forthe cross section of the rod based on the basic size. Steel data are available in Table A-10 from thetextbook.Condition #2:The same structural support of the basic size determined in Condition 1 is subjected to a tensile load of15 kN that is repeated several thousand times over the life of the machine. This load is not an addition tothe 20 kN. Specify a suitable steel that is suitable to this application based on the basic size determined inCondition #1. Loading of Condition W1 does not apply here.Condition #3:The same structural support from Condition 2 is heated from room temperature of 25°C. The support isplaced inside a frame on both ends. There is a total clearance of 0.2 mm between the support and itsframe. Initial length of the rod is 200 mm. Specify the maximum temperature that the support can beheated to without exerting any stress to the frame.
