5. If an Acme-thread power screw is loaded in tension with a force of 30 000 lb, what size screw from Table 17-1 should be used to maintain a tensile stress below 10 000 psi? 6. For the screw chosen in Problem 5, what would be the required axial length of the nut on the screw that transfers the load to the frame of the machine if the shear stress in the threads must be less than 6000 psi? 7. Compute the torque required to raise the load of 30 000 lb with the Acme screw selected in Problem 5. Use a coef- ficient of friction of 0.15.
