A steel wire of length 2.5 m and area of cross section `1.25 mm^(2)`, when it is stretched by a force of 40 N and Y for steel is `2xx10^(11)N//m^(2)`. The extension produced in a steel wire is

A steel wire of length 5 m and area of cross-section 4 mm^(2) is stretched by 2 mm by the application of a force. If young's modulus of steel is 2xx10^(11)N//m^(2), then the energy stored in the wire is

A steel wire of length 5 m and area of cross-section 4 mm^(2) is stretched by 2 mm by the application of a force. If young's modulus of steel is 2xx10^(11)N//m^(2), then the energy stored in the wire is

On increasing the length by 0.5 mm in a steel wire of length 2 m and area of cross section 2 mm^2 , the force required is [Y for steel =2.2xx10^11(N)/(m^2) ]

A unifrom steel wire of length 6 m and area of cross section 2 mm^(2) is elastically strectched through 3 mm. Calculate the energy stored in the wire. [Y_("steel") = 2xx 10^(11) N//m^(2)]

A steel wire 4 m in length and 2.4*10^(-7)m^2 in cross - section is stretched by a force of 36N . Calculate the stress and strain .
