PROBLEM #$2$

A $50-$m steel tape was used to measure a line and the initial pull $=5\mathrm{.}7kg.$ Pull at time of

measurement $=8\mathrm{.}0kg.$ Weight of tape $=0\mathrm{.}05k\frac{g}{m}.E=2\mathrm{.}3{10}^{6}k\frac{g}{c}{m}^2.$ Cross section $=0\mathrm{.}04sq.cm.$

Measured distance between two points $=488\mathrm{.}650m.$ in an inclined surface having a gradient of

$3\%.$ Find the correct horizontal distance between the two points.
