1. A jack having square threads of 50 mm nominal diameter and 10 mm pitch is supporting a load of 89 kN. A double thread is used and the coefficient of friction maybe as low as 0.10 or as high as 0.15.a. Will this screw always self-locking?b. What is the highest torque necessary to raise the load?
Determine the safe tensile load for fine series bolts of (a) M 24and (b) M 38. Assume that the bolts are not initially stressed and take the safe tensile stress as 450MPa.
The figure illustrates the connection of a steel cylinder head to a grade 30 cast-iron pressure vessel using N bolts. A confined gasket seal has an effective sealing diameter D. The cylinder stores gas at a maximum pressure pg. For the specifications given in the table for the specific problem assigned, select a suitable bolt length from the preferred sizes in Table A–17, then determine the yielding factor of safety np, the load factor nL, and the joint separation factor n0. See problem number 8-36, and please use the FEA exponential curve-fit for member stiffness.
