In above problem, if Poiddon's ratio is `sigma =0.1` .Find the change in diameter.

A

`31. 84 xx 10^(-5)`

B

`31.84 xx 10 ^(-5) m`

C

` 3.184 xx 10 ^(-8)m`

D

` 3.184 xx 10^(-8) m`

Text Solution

Verified by Experts

The correct Answer is:
C
(c)`therefore sigma=(DeltadL)/(dDeltaL)`
`therefore Deltad=(sigmadDeltaL)/(L)=(0.1xx2xx10^(-3)xx31.84xx10^(-5))/(2)=31.85xx 10^(-8) m`
