Problem 1: 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...
