Draw the not-yielding envelope of MSS and DE theory, and then
show all the load lines. Please show the yield strength data in
your graph along with other data. You need to use free-hand-sketch
to draw the DE based envelope.
A ductile hot-rolled steel bar has a minimum yield strength in tension and compression of 350 MPa Using the distortion-energy and maximum-shear-stress theories determine the factors of safety for the following plane stress states (a) 100 MPa, a, = 100...
5-36 This problem illustrates that the factor of safety for a machine element depends on the particular point selected for analysis. Here you are to compute factors of safety, based upon the distortion- energy theory, for stress elements at A and B of the member shown in the figure. This bar is made of AISI 1006 cold-drawn steel and is loaded by the forces F = 0.55 kN, P = 4.0 kN, and T = 25 N·m. -100 mm- Problem...
Consider a cantilevered steel bar shown below. The bar must support a static load P of 900 lb and steel with a yield point of 68 kpsi will be selected for the bar. Assume the selected steel is ductile, even material and the stress concentration can be neglected, but a safety factor of 6.0 should be used. * d = ?
