A rubber cube of side 5 cm has one face fixed while a tangential force 1800 N is applied on its opposite face. If modulus of rigidity of rubber is 2 . 4 × 10 6 N m - 2 , then the lateral displacement of the strained face is______.

Question

A rubber cube of side 5 cm has one face fixed while a tangential force 1800 N is applied on its opposite face. If modulus of rigidity of rubber is 2 . 4 × 10 6 N m - 2 , then the lateral displacement of the strained face is______., 3 mm, 5 mm, 15 mm, 1 . 5 mm

MARKS App · Accepted Answer

Recall the formula of modulus of rigidity, η = F A × L l = 1800 25 × 10 - 4 × 5 × 10 - 2 l = 2 . 4 × 10 6 l = 1800 25 × 10 - 4 × 5 × 10 - 2 2 . 4 × 10 6 = 15 mm
