Question

Professor PC Thomas Classes · Answer

The breaking stress is a constant for a material. Let F be the maximum force and A the area of cross-section. Then breaking stress $=\frac{\mathrm{F}}{\mathrm{A}}$ Here $\frac{\mathrm{F}_{1}}{\mathrm{~A}_{1}}=\frac{\mathrm{F}_{2}}{\mathrm{~A}_{2}}$\ $\mathrm{A}_{1}=\mathrm{A}_{2} \quad 	herefore \mathrm{~F}_{1}=\mathrm{F}_{2}$\ The maximum load which a wire can support is independent of the length.\
