Question

area of cross section of a wire of length 1.1 metre is 1 mm square it is loaded with 1 Kg if Young's modulus of copper is 1.1 into 10 to the power 11 Newton per metre square then the increase in length will be ​

Answer 1

The increase in the length of the wire is Δl = 0.1 mm

Explanation:

Given data:

Length of wire = 1.1 m

Area of cross section = 1 mm

Young's modulus of copper "Y"= 1.1 x 10^11 N

To find: Increase in length

10 x 1 = 10 N

Stress = Y x Strain

10 /1 x 10^-6 = 1.1 x 10^11 x Δl / 1.1

Δl = 10^7 x 10^-11

Δl = 10^-4  m

Δl = 0.1 / 1000 m

Δl = 0.1 mm

Thus the increase in the length of the wire is Δl = 0.1 mm
