A steel rod of length 1 m rests on a smooth horizontal base. If it is heated from `0^@C` to `100^@C`, what is the longitudinal strain developed?

Explanation

To solve the problem of finding the longitudinal strain developed in a steel rod heated from \(0^\circ C\) to \(100^\circ C\), we can follow these steps:

### Step 1: Understand the Concept of Longitudinal Strain
Longitudinal strain is defined as the change in length of the rod divided by its original length. It can be expressed mathematically as:
\[ \text{Longitudinal Strain} = \frac{\Delta L}{L_0} \]
where \(\Delta L\) is the change in length and \(L_0\) is the original length.
