Question

State whether true or false :
The hollow shaft is much stronger than a solid shaft of same mass, same length and same material.

• A. True
• B. False

Answer 1

The correct option is A True

Modulus of elasticity = $\frac{stress}{strain}$ and, stress = $\frac{Force}{Area}$

$\therefore$ Elasticity $\alpha \frac{1}{Area}$

As follow shaft, so, elasticity of the follow shaft is more than a solid one. As elasticity measures rigidity. So, hollow shaft is stronger.
