A steel wire `2 m` long is suspended from the ceiling. When a mass is hung at its lower end, the increase in length recorded is `1 cm`. Determine the strain in the wire.

A

1 cm

B

`1.5 cm`

C

2cm

D

`0.5 cm`

Text Solution

Verified by Experts

The correct Answer is:
B
Strain `= (delta L)/(L) :. delta L = 0.01 xx 150 = 1.5 cm`

A steel wire 2 m long is suspended from the ceiling. When a mass is hung from its lower end, the increase in length recorded is 1 cm . Determine the strain in the wire.

Steel wire of length 'L' at 40^@C is suspended from the ceiling and then a mass 'm' is hung from its free end. The wire is cooled down from 40^@C to 30^@C to regain its original length 'L'. The coefficient of linear thermal expansion of the steel is 10^-5//^@C , Young's modulus of steel is 10^11 N//m^2 and radius of the wire is 1mm. Assume that L gt gt diametere of the wire. Then the value of 'm' in kg is nearly
