Question

A cylindrical wire is twisted with an angle $\theta$, what is torsion produced in it?

• A. $\frac{C}{\theta }$
• B. $C\theta$
• C. $\frac{C}{{\theta }^2}$
• D. $C{\theta }^{3/2}$

Answer 1

Answer: (B)

The torsion produced in wire is directly proportional to the twist
i.e, $\tau \propto \theta$
or $\tau =C\theta$, where C is restoring couple per unit twist
