Answer to relevant QuestionsRepeat Prob. 6–12 but with a steady torsional stress of 103 MPa, an alternating torsional stress of 69 MPa, and an alternating bending stress of 83 MPa.Repeat Prob. 6–17, with the load fluctuating between 800 and -3000 lbf. Assume no buckling.A 30-tb block is initially moving along a smooth horizontal surface with a speed of v1 = 6 ft/s to the left. If it is acted upon by a force F, which varies in the manner shown, determine the velocity of the block in 15 s.A schematic of a clutch-testing machine is shown. The steel shaft rotates at a constant speed ω. An axial load is applied to the shaft and is cycled from zero to P. The torque T induced by the clutch face onto the shaft ...A 5/4 -in-diameter hot-rolled steel bar has a 1/8 -in diameter hole drilled transversely through it. The bar is nonrotating and is subject to a completely reversed bending moment of M = 1600 lbf • in in the same plane as ...
