Question

5. A solid steel shaft has a diameter of 200mm. The shaft transmits 550kW at 300r/min. It is also subjected to a bending moment of 10kNm and an end thrust of 400kN. Find:

5.1 The applied torque

5.2 The applied shear stress

5.3 The applied bending stress

5.4 The stress due to the end thrust

Draw a stress element and matching Mohr’s circle clearly showing Both principle stresses and the maximum shear stress at:

5.5 the top of the shaft’s cross section

5.6 the middle of the shaft’s cross section

5.7 the bottom of the shaft’s cross section.

Calculate:

5.8 the equivalent bending moment

5.9 the maximum principle stress using the equivalent bending moment

5.10 the equivalent torque

5.11 the maximum shear stress using the equivalent torque

OBS: Please start from 5.4 to 5.11. Do it in an organized and comprehensive manner. Make sure to include explanation for most important points. Pls do it as soon as possible, I'm writing Applied Strength test  Tomorrow morning (South Africa time). It's now 14:37 over here. I need to get ready. Thanks.
