Chapter 5.10, Problem 120P

The steel step shaft has an allowable shear stress of Fallow 9 MPa. If the transition between the cross-sections has a radius r-4 mm, determine the maximum torque T that can be applied. Take K-1.25. 20 mm 72 N.m T 50 mm 20 mm 7/2 The maximum torque T that can be applied is. Note: Please enter your answer with three significant digits after the decimal point. Take the torque as positive since the problem does not have multiple sections before the step.

The electric motor exerts a torque of 800 N- m on the steel shaft ABCD when it is rotating at a constant speed. The angle of twist between A and D is limited to 1.50 degree. Use maximum shear = 60 MPa and modulus of rigidity = 77 GPa. Solve its torque for each shaft AB and BC. And determine the diameter of the Shaft based on strength. 300 N.m 500 N.m 0.4 m 0.6 m 0.3 m

The steel shaft is formed by attaching a hollow shaft to a solid shaft. Determine the shear stress (in Pa) in the hollow shaft using the maximum torque T that can be applied to the ends of the shaft without exceeding a shear stress of 70066350 Pa and angle of twist of 2.5° for the whole shaft. Use 6 = 83000000000 Pafor the shaft, x = 2.25 m, and y = 1.63 m. Round off the final answer to two decimal places. T 100 mm 70 mm 70 mm y
