Hi there,
I'm trying to find a solution to a problem that I thought was straight forward, but am now struggling with.
I've got a shaft with a fixed end set up, where there is a small diameter fixed and then it steps up to a larger diameter which is having a torque applied to it.
I'm trying to find out the maximum torque that can be applied to the larger side before the material starts to shear.
The only things that i know about the shaft are the diameters and material type.
So far I've been using:
T=(τ*J)/r
and
τ=0.557*σ
Where:
T = maximum torque
τ = allowable shear stress
J = polar moment of inertia
r = radius
σ = ultimate tensile strength.
Can anybody help me out? I'm not sure if I've got the equations right or whether I'm going down the correct route.
Cheers
