A rectangular metallic block of dimensions 40 ~mm 20 ~mm when pulled with a tension of 50 kN undergoes only elastic deformation. The strain in the block is (The shear modulus of the material of the block is 40 10^9 Nm ⁻² )
Options
- A1.56 10⁻³ ~m
- B2.4 10⁻³ ~m
- C3.2 10⁻³ ~m
- D1.08 10⁻³ ~m
Correct answer
A. 1.56 10⁻³ ~m
Step-by-step solution
Tension, F =50 10^3 ~N Area, A=40 20 10⁻⁶ M aligned & Modulus of the material = Stress Strain & Strain = Force Area shear modulus aligned = 50 10^3 40 20 10⁻⁶ 40 10^9 =1.5 10⁻³ ~m
