The work done per unit volume to stretch the length of area of cross-section `2 mm^2` by 2% will be

Work done per unit volume is stretching a wire

The work done per unit volume in stretching the wire is equal to

The work per unit volume to stretch the length by 1% of a wire with cross sectional area of 1mm^2 will be. [Y=9xx10^(11)(N)/(m^2) ]

The work per unit volume to stretch the length by 1% of a wire with cross sectional area of 1mm^2 will be. [Y=9xx10^(11)(N)/(m^2) ]

The work done per unit volume in stretching a wire is equal to

Give the expression for work done per unit volume in stretching a wire.

If Young.s modulus of the material of a wire is 1.2xx10^(11) Nm^(-2) , calculate the work done in stretching the wire of length 3 m and cross-sectional area 4mm^(2) when it is suspended vertically and a load of 8 kg is attached to its lower end.

The work done in increasing the length of a one metre long wire of cross-sectional area 1 mm^(2) through 1 mm will be (Y = 2 xx 10^(11) Nm^(-2))
