Shaft diameter
Thread Content
With the same material and the same torque, can the hollow shaft bear the same torque as the solid shaft? How do I calculate if I want to replace a solid shaft with a hollow shaft? Ask the experts!
When the diameters are the same, can the hollow shaft withstand a smaller torque than the solid shaft? Find the moment of inertia π of the original solid shaft* d^3/16 and the moment of inertia π of the hollow shaft with a larger diameter * (doutside^3-dinside^3)/16. Take the inner and outer diameter of the hollow shaft "doutside/dinside" to calculate the moment of inertia not less than the original solid shaft.
