Introduction to Twisting
Torsion(N)
Twisting due to an applied torque
Torque(Nm)
A twisting force
Shaft
A long slender structural member subjected to a torque about it’s long axis
Torsional Stress
Torque applied to the end of a shaft
Shaft twists an angle θ
θ is a function of shaft length L and stiffness G (shear modulus)
θ starts at zero and increases linearly as a function of X (as get further from pivot position)
γ (inner core angle) is constant along length (x)
(Shear) Stress is at maximum at the Radius (edge of the material)
