A stell wire of 1m long `1mm^(2)` cross section area is hang from rigid end. The length of 1kg is hung from it then change in length will be (given `Y = 2 xx 10^(11) N//m^(2)`)

Work done in stretching a wire of length 1 m and of cross-sectional area 1 mm^(2) through 2 mm if Young's modulus of the material of the wire is 2 xx 10 ^(11) N//m^(2) is .......

If a copper wire of length 0.9 m and cross section 1mm^(2) is stretched by a load of 1 kg then the extension in the wire will be (Y_(c )=1.2xx10^(11)N//m^(2) and g=10m//s^(2))

When a force is applied on a wire of uniform cross-sectional area 3xx10^-6m^2 and length 4 m, the increase in length is 1mm. Energy stored in it will be (Y=2xx10^(11)(N)/(m^2) )

When a force is applied on a wire of uniform cross-sectional area 3xx10^-6m^2 and length 4 m, the increase in length is 1mm. Energy stored in it will be (Y=2xx10^(11)(N)/(m^2) )

What is the force requiredto stretch a steel wire of 1 cm^(2) cross-section to 1.1 times its length ? (Y = 2 xx 10^(11) N//m^(2))

A wire of length L and cross section A hung from a rigid support is loaded with a mass M The elongation produced is
