Question

What is torsional strength?

Answer 1

1. Torsional strength is the ability of the material to withstand the twisting load.
2. When the material is subjected to torsional loading, torsional strength is the maximum torsional stress that the material can withstand before rupture.
3. When subjected to torsional force It is the ultimate strength of a material as well as the maximum torsional stress that a material can withstand before rupturing.
4. Mathematically it is given as,

Torsional strength $=\frac{\text{rotational force}}{\text{cross-sectional area}}$

5. It is the amount of torsional stress that a body can withstand before failing.
