Hi, thanks for looking! Appreciate it!
Right, the question is
For a HOLLOW shaft determine, max torque induced, pilot second moment of area, max shear stress at outer edge, and max angle of twist induced in the shaft, with a material modulus of rigidity of 110 GN/m2. Given that-
Shaft diameters, 160mm and 140mm, length 650mm, power 350kw at 3500rpm.
I have calculated all of these and got what look to be reasonable answers, but the second part of the question is, if you were to replace the hollow shaft will a solid shaft, what would the diameter of the new shaft be? If it were to perform the same duty of max torque and max shear stress.
I have no formula for working this out??
The only info I have is-
T\J = ζ/r
Hope someone can help, thank you!
