Hi,

Torsion is a very important to run the vehicles with the wheels. Torsion is required almost in every day to day activities.

For Mechanical and Civil Engineers, the concept of torsion is very important to understand.

Torsion is the amount of couple/moment which is required to rotate a given section through the specified degrees about its polar axis.

In the figure below T is the amount of torque required to rotate a circular section at distance equal to 'L'through an specified angle.

It depends upon Polar moment of Inertia of the section "J". If we analyse the mechanism we get a relationship between, shear stress(t), radial distance(r), Torsion(T), Polar moment of Inertia(J), Modulus of rigidity(G), angle of rotation(@) of the circular section and length(L) as follows:

t/r= T/J = G.@/ L

J is the moment of inertia about the normal axis.

Thanks for your kind visit!
