Question 1 Shaft AB is supported at B by a roller support and at A by a pin support as well as a spline that prevents rotation around x axis. The diameter of the shaft is D. At cross section A-A there is a relief groove where the minimum diameter is d. Two loads, F, and one torsion moment, T, are acted on the shaft. The material of the shaft is aluminum 7075, Sy = 495 MPa. Also known: L=630...

A beam may have zero shear stress at a section but may not have zero deflection; Hence, bending is primarily caused by bending moment In Torsion loading a stress element in a circular rod is subject to shear state The principal plane and the plane on which the shear stresses are maximum, they make 90 degree angle between them. If the Torque on a steel circular shaft (G=80 GPa) is 13.3 kN-m and the allowable shear stress is 98 MPa,...

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...
