Question: Repeat Prob 6 12 but with an alternating
Repeat Prob. 6–12 but with an alternating torsional stress of 207 MPa.
Answer to relevant QuestionsRepeat Prob. 6–12 but with an alternating torsional stress of 103 MPa and a steady bending stress of 103 MPa.The figure shows a formed round-wire cantilever spring subjected to a varying force. The hardness tests made on 25 springs gave a minimum hardness of 380 Brinell. It is apparent from the mounting details that there is no ...The figure is a drawing of a 3- by 18-mm latching spring. A preload is obtained during assembly by shimming under the bolts to obtain an estimated initial deflection of 2 mm. The latching operation itself requires an ...A flat leaf spring has fluctuating stress of σmax = 420 MPa and σmin = 140 MPa applied for 5 (104) cycles. If the load changes to σmax = 350 MPa and σmin = .200 MPa, how many cycles should the spring ...The plan view of a link is the same as in Prob. 6–23; however, the forces F are completely reversed, the reliability goal is 0.998, and the material properties are Sut = 64LN (1, 0.045) kpsi and Sy = 54LN (1, 0.077) kpsi. ...
