NCERT · Class 11 · Physics · Mechanical Properties of SolidsWhat is the value of Young's modulus for a perfectly rigid body?
Step-by-Step Solution
For a perfectly rigid body, no strain is produced regardless of the applied force (Strain = 0). Since Young's Modulus $Y = \frac{\text{Stress}}{\text{Strain}}$, $Y = \frac{\text{Stress}}{0} = \infty$ (Infinity).
