A steel wire is 4.0 m long and 2 mm in diameter. Young’s modulus of steel is `1.96 xx 10^(11) N//m^(2)`. If a mass of 20 kg is suspended from it the elongation produced will be-

Young 's modulus of steel is 2.0 xx 10^(11)N m//(2) . Express it is "dyne"/cm^(2) .

Young 's modulus of steel is 2.0 xx 10^(11)N m//(2) . Express it is "dyne"/cm^(2) .

Two wires of diameter 0.25 cm , one made of steel and other made of brass, are loaded as shown in the figure. The unloaded length of the steel wire is 1.5 m and that of brass is 1.0 m . Young's modulus of steel is 2.0 xx 10^(11) Pa and that of brass is 1.0 xx 10^(11) Pa. Compute the ratio of elongations of steel and brass wires. (/_\l_("steel"))/(/_\l_("brass"))=?

A spring is made of material of Young's modulus 10^(11)N//m^(2) . When a weight of 10 kg is suspended vertically the elongation produced in the spring is 4 mm. If the load is reduced to half the elongation in the spring will be

How much will a steel wire 2m long and 1mm diameter stretch under a 5 kg wt. load ? (Y = 2 xx 10^11 N/m^2)

A steel wire 4.0m in length is stretched through 2.0mm .The cross -sectional area of the wire is 2.0 mm^(2) .If young's modulus of steel is 2.0xx10^(11) N//m^(2) (a) the energy density of wire, (b) the elastic potential energy stored in the wire.
