Question: Repeat Prob 6 12 but with
Repeat 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.
Answer to relevant QuestionsRepeat Prob. 6–12 but with an alternating torsional stress of 207 MPa.If it takes 35s for the 50-Mg tugboat to increase its speed uniformly to 25 km/h, starting from rest, determine the force of the rope on the tugboat. The propeller provides the propulsion force F winch gives the tugboat ...The rocket sled has a mass of 3 Mg and starts from rest when t = 0. If the engines provide a horizontal thrust T which varies as shown in the graph, determine the sled’s velocity in t = 4 s. Neglect air resistance, ...For the clutch of Prob. 6–27, the external load P is cycled between 20 kN and 80 kN. Assuming that the shaft is rotating synchronous with the external load cycle, estimate the number of cycles to failure. Use the modified ...Repeat Prob. 6–36, with the bar subject to a completely reversed torsional moment of 2400 lbf • in.
