STEP 0: Pre-Calculation Summary
Formula Used
Torque = (Modulus of Rigidity*Angle of Twist*Polar Moment of Inertia)/Length of Shaft
T = (GTorsion*θ*J)/Lshaft
This formula uses 5 Variables
Variables Used
Torque - (Measured in Newton Meter) - Torque is a measure of the force that can cause an object to rotate about an axis.
Modulus of Rigidity - (Measured in Pascal) - Modulus of Rigidity is the measure of the rigidity of the body, given by the ratio of shear stress to shear strain. It is often denoted by G.
Angle of Twist - (Measured in Radian) - Angle of twist is the angle through which the fixed end of a shaft rotates with respect to the free end.
Polar Moment of Inertia - (Measured in Meter⁴) - Polar Moment of Inertia is the moment of inertia of a cross-section with respect to its polar axis, which is an axis at right angles to the plane of the cross-section.
Length of Shaft - (Measured in Meter) - Length of Shaft is the distance between two ends of shaft.
STEP 1: Convert Input(s) to Base Unit
Modulus of Rigidity: 40 Gigapascal --> 40000000000 Pascal (Check conversion ​here)
Angle of Twist: 1.42 Radian --> 1.42 Radian No Conversion Required
