A low carbon steel shaft is designed to have a diameter of 30 mm. It is to be subjected to an axial load (P-30 kN), a moment (M-200 N-m), and a torque (T-300 N-m). Assume the yield stress for the steel is (280 MPa), the Poisson's ratio is (v= 0.29), and the safety factor is (1-1). Calculate the margin of safety using the following failure theories. a.) Rankine Criteria (Maximum Principal Stress) b.) Tresca Criteria (Maximum Shear Stress) c.) Saint...
The solid steel shaft DF has a diameter of 25 mm and is supported by smooth bearings at D and E. It is coupled to a motor at F, which delivers 12 kW of power to the shaft while it is turning at 60 rev/s.The gears A, B, and C remove 3 kW, 4 kW, and 5 kW respectively. The shaft is free to turn in its support bearings D and E. (Figure 1) Part A Determine the absolute maximum...

The figure shows a transmission shaft. The steel solid shaft is 200 mm long between self-aligning bearings at A and B. Belt forces (in the same horizontal direction) are applied to a 120-mm diameter sheave at C. The left end of the shaft is connected to an electric motor attached to a clutch by means of a flexible coupling. Nothing is attached to the right end (it is free). Assuming the shaft has a constant diameter, d, (a) Perform the...
A 60-mm diameter solid 1030 cold-drawn and machined steel shaft is mounted on anti-friction roller bearings modeled as simple supports and carries two pulleys with belts wrapped B = 150° at a constant, non-critical speed. The shaft has the yield, ultimate and endurance limit strengths of 1030 cold-drawn steel. It is required that the shaft has infinite fatigue life. It is also required that deflection not exceed 1.5 mm at any point and that the maximum angle of twist not...
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...
Problem 1 (25 Points) Two solid steel (6-80 GPa) shafts are connected by the gears shown. Shaft (1) has a diameter of 45 mm, and shaft (2) has an outside diameter of 55 mm and wall thickness 4 mm. Assume that the bearings shown allow free rotation of the shafts. If a 400 N-m torque is applied at gear D, determine (a) the maximum shear stress magnitudes in each shaft.
