Mechanical Properties Of Fluids

Question

Wired Faculty App

How much length of a rod of length 1 m increases when heated through 1°C?

Solution

The increase in the length of rod is,

increment ell space equals space ell αθ space space space space space space space equals space 1 cross times straight alpha cross times 1 space space space space space space space equals space straight alpha

That is,
Increase in the length is equal to the temperature coefficient of linear expansion.
