A cube has side length \(5\) cm and modulus of rigidity \(10^5\) N/m\(^2\). The displacement produced by a force of \(10\) N in the upper face of cube is _____ mm.
- A 2
- B 3
- C 4
- D 5
Answer & Solution
Correct Answer
(A) 2
Step-by-step Solution
Detailed explanation
Given: Side length of the cube, \(L = 5\) cm \(= 0.05\) m Modulus of rigidity, \(\eta = 10^5\) N/m\(^2\) Force applied on the upper face, \(F = 10\) N Area of the upper face, \(A = L^2 = (0.05)^2 = 2.5 \times 10^{-3}\) m\(^2\) Shear stress is given by:…
