Automobile Designer Interview Question:

Tell me in order to derive the torsional formulas what are the assumptions taken?

Submitted by: Muhammad

The torsion equation is derived on the basis of following assumptions:
☛ > The shaft material is uniform, throughout the shaft.
☛ > Even after loading the shaft circular remains circular.
☛ > After the application of torques the plain section of a shaft remains plain.
☛ > Any twist that occurs in the shaft remains uniform and constant.
☛ > After the application of torque the distance between any two cross-sectional references remains constant.
☛ > The elastic limit value of a shaft is never exceeded even after the
