Assignment Help Mechanical Engineering
Reference no: EM13886997

 For a torsion test, derive equations relating the angle, ψ, between the axis of the largest principal stress and the axial direction and the angle, ψ !, between the axis of the largest principal strain and the axial direction in terms of L, r, and the twist angle, θ. Note that for ?nite strains, these two angles are not the same.
