Suppose I have a motor driving a shaft that runs 1.5m long with a screw attached, the screw is mixing a product.(adsbygoogle = window.adsbygoogle || []).push({});

Power = Torque x Speed

Torque = Power/Speed

To find my Torque I can use my Shear Max = Tr/J

And J for a shaft isTmax = (π / 16)max D3τ

My question is, where does the mass of the shaft itself come into the formula? And How would I calculate the force the product is causing on the screw attached to the shaft?
