# Circular Shaft Maximum Torque Calculator

Posted by Dinesh onOnline calculator to calculate twisting moment in circular shaft using circular shaft maximum torque formula.

An important use of shafts is to transmit power between parallel planes, as in automobile power trains, electrical machinery, aircraft engines or helicopter rotors. A torqued haft produces a relative rotation of one end respect to the other; This relative rotation is called the twist angle ?.

## Twisting Moment in Circular Shaft Calculation

### Formula:

T_{max} = (?_{max} × (J / R))

**Where,**,

?_{max} = Maximum shear stress,

J = Polar moment of inertia of an area,

R = Radius of shaft,

T_{max} = Twisting moment
