Question details

Homework #1 MEEM 4170 1 A hollow cylindrical 4340 steel member of 1 inch od and 30 inches long with a one- quarter-inch wall is simply supported at the ends and symmetrically loaded at the one-third points by 1000 Ib loads. The bar is simultaneously subjected to an axial force of 5000 Ib and a torsional moment of 3000 in-lb. For the critical point at the center of the bar, determine the principal stresses, principal planes, principal shearing stresses, and planes of principal shear. 1000 lb1000 Ib 1.0 inch o.D x 0.25 inch thick wall F. 5000 lb M, - 3000 in.-lb 10 inches 10 inches10 inches A solid cylindrical bar of 1020 steel is 30 inches long and 1.5 inches in diameter. The bar is simultaneously subjected to a pure bending moment of 10.600 in-lb and a pure torsional 2.
