1.1-in din. 1.5-india 3. A round shaft supports a transverse load of F = 15 000 lbf and carries a torque of T = 7 kipin, as shown in the figure. The shaft does not rotate. The shaft is machined from AISI 4140 steel, quenched and tempered at 400°F. Document the location of the critical stress element and how you determined that element to be critical. Do not assume transverse shear stress is negligible without proving it. Then, (a) determine...

A shaft with a diameter of 43 mm, is shown below On the right
hand side at location D a wheel has a force F of 4824N applied. The
diameter of this wheel is 150 mm. The torque produced by F is
transmitted through the entire shaft to location A where the torque
is reacted. There are no other constraints at location A. Bearings,
are located at B and C, and provide radial constraint. The bearing
at B also provides...
