A load of 7.6kg hangs from the lower end of a stell wire is reigly clamped at the upper end. When the load immersed in wate, the length of the wire changes by 1mm. Calculate the length of the wire.. (Young's moduls of steel =`2 ss 10^(11) Nm^(-2)` diameter of the wire -0.4mm density if neterual of material of load =`7600kg m^(-3) and g=9.8ms^(-2)`.
