The Strain Energy , If The Torsion Moment Value Is Given
Strain energy is defined as the energy stored in a body due to deformation.
The strain energy per unit volume is known as strain energy density and the area under the stress-strain curve towards the point of deformation
Where,
T = Applied Torsion
L = Length of the beam
G = Shear modulus or Modulus of rigidity
J = Polar moment of inertia
