The normal tension which will be applied to o tape supported over two supports in order to make the tape equal to its normal length when supported only at the end points. The steel tape is $30-$m long and weighs $1\mathrm{.}5$kg when supported throughout its length under a standard pull of $6$kg with the modulus o elasticity of $2$x$106$ kg$/$cm$?$ and an area of $0\mathrm{.}05$cm$218.$ Compute the linear density of the tape in kg$/$m$.$
