The followings are assumptions about torsional deformation of a circular shaft, EXCEPT

Deformation is linear

Deformation is elastic

Deformation becomes plastic

Plane section remains planar and undistorted

The torsion formula is given as $\tau=\frac{T\rho}{J}$ . Which of the followings are CORRECT?

[Choose ALL which applicable]

T is internal torque

$\rho$ is distance from centre of the cross-section to any point on the plane

J for SOLID shaft is $J=\frac{\pi}{2}\left(c_0^2-c_i^2\right)$

The shear stress has linear distribution

m/sec

rev/min or rpm

rad/sec
