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...

75 mm 1.5 m T = 48 N·m 2 m 150 mm Two solid steel 20-mm-diameter shafts are coupled together using the perfectly meshed gears shown. Shaft DC is fixed to the wall at D and supported with a frictionless journal bearing. Shaft EF is supported with two frictionless journal bearings. The modulus of rigidity of steel is 80 GPa. Before the torque is applied, the angle of twist in each shaft is zero, and the angle of rotation of...

Question 2 (25 marks) A square wood platform of side-length L = 2.4 m rests on masonry walls. The deck of the platform is constructed of 4 cm thick planks supported on two beams which are 2.4 m long. The beams have a width of 100 mm and height of 150 mm and are supported at their ends by the walls. The structure is designed to support a uniformly distributed load, wA (kN/m2), acting over the entire top surface of...
