Question

Write the expression of torsional rigidity of wire?
​

Answer 1

Explanation:

where I p = π D 4/32 is the polar moment of inertia of a circular cross section. Thus, combining Equations (6.8) and (6.14) we have. Thus, the torque required for unit twist, i.e., T (θ) is called the torsional stiffness. From the above relation, The quantity is known as torsional rigidity and is represented ...

Answer 2

Answer:

• Torsional rigidity = G x J.

Explanation:

• The applied torque needed to produce a unit angle of twist in a circular elastic material; a measure of a body's resistance to torsion

• The torsional rigidity shows the resistance offered by a material to angular deformation. Torsional rigidity is also defined as the torque required to produce a unit radian angle of twist per unit length of the shaft. The term torsional rigidity is expressed as, Torsional rigidity = G x J.
