Question

A metallic cube of Side 5 cm, has its lower
surface fixed rigidly. When a tangential Force
of 104 kg .wt. is applied to the upper sur
Face sito is displaced through 0.03 mm.
Calculate
The shearing stress
2) The shearing strain
3) The modulus of rígidity of the metal​

Answer 1

Answer:

Correct option is

C

1.96×104N

On the verge of toppling, the normal will shift towards right most point of edge.

Torque about the edge: 

2L×3.2×103=F×1.2

(0.75)(3⋅2×103×9.8)=F×1.2

F=1.96×104N
