Question

a metal bar is 2m long.When 5.5 tonne is applied its length become 1.995m. find the compressive strain
​

Answer 1

Answer:

metal bar 2m

tonne is applied 5.5

1.95mm28098

Answer 2

Given:

Force (F) = 5.5 KN

Original length (L₁) = 2 m

Final Length (L₂) = 1.995 m

To find:

The compressive strain.

Solution:

Change in length (δl) = 2 m - 1.995 m

δl =  0.005 m

Compressive strain = Change in length / Original length

Compressive strain = δl / L₁

Compressive strain = 0.005 m / 2 m

Compressive strain = 0.0025

Therefore, the compressive strain is equal to 0.0025.
