I think I'm over thinking this, so someone set me straight.
If I have an eletric motor with a 75mm OD shaft making 1450Nm of torque, and
I add a 7in pulley/sheave to the motor shaft.
Would the torque change? Half of me says yes other half of my brain thinks no.
Torque = Force * distance
1450Nm/(0.075m/2)=19333.3N at the edge of the motor shaft.
Now at the 7in Pulley that is bolted to the shaft
19333.3N*0.0889m= 1718.73Nm (0.0889m--> 3.5in-->half of 7in pulley)
Is this right? or would you still have the 1450Nm of torque at the 7in pulley?
