Vedclass · Answer

If $\mathrm{F}, \mathrm{L}, \mathrm{Y}$ are constant then $\ell \propto(1 / \mathrm{A})$

i.e. $\ell \propto\left(1 / r^{2}\right)$

i.e. for same load, thickest wire (radius is more) will show minimum elongation.

From the graph, minimum elongation is shown by graph $OD.$

Hence OD must be thickness wire's graph.

The load versus strain graph for four wires of the same material is shown in the figure. The thickest wire is represented by the line
