MCQ
Young’s modulus of perfectly rigid body material is
- AZero
- ✓Infinity
- C${\rm{1}} \times {\rm{1}}{{\rm{0}}^{{\rm{10}}}}\,N/{m^2}$
- D${\rm{10}} \times {\rm{1}}{{\rm{0}}^{{\rm{10}}}}\,N/{m^2}$
The Strain produced in a perfectly rigid body is zero i.e Strain$=0$
$\therefore Y=\frac{S t r e s s}{0} \quad \Longrightarrow Y=\infty$
Thus the Young's modulus of perfectly rigid body material is infinite.
