A load of 1 kg weight is a attached to one end of a steel wire of area of cros-section `3 mm^(2)` and Young's modulus `10^11 Nm^-2`. The other end is suspended vertically from a hook on a wall, then the load is pulled horizontally and released. When the load passes through its lowest position the fractional change in length is `(10ms^-2)`

A load o f 1 kg weight is a attached to one end of a steel wire o f area of cross-section 3mm^(2) and Young's modulus 10^(11) N//m^(2) . The other end is suspended vertically from a hook on a wall , then the load is pulled horizontally and released .When the load passes through its lowest position the fraction al change in lenght is (Take g = 10m//s^(2))

A load of 1kg weight is attacheed to one end of a steel wire of cross sectional area 3mm^(2) and Young's modulus 10^(11) N//m^(2) . The other end is suspended vertically form a hook on a wall, then load is pulled horizonatally and relased. When the load passes through its lowest position the fractional change in length is (g = 10m//s^(2))

A sphere of mass 2 kg and diameter 4.5 cm is attached to the lower and of a steel wire of 2 m length and are of cross- section 0.24 xx 10^(-6)m^2 . The wire is suspended from 205 cm high ceilling of a room. When the system is made to oscillate as a simple pendulum, the sphere just grazes the floor at its lowest psition. The velocity of the sphere at the lowest position is (young's modulus of steel =2xx 10^(11) Nm^(-2) and acceleraiton due to gravity =10 ms^(-2))

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

A spring of young's modulus 2 xx 10^11 pa is suspended vertically and subjected to a load of 5 kg and elongation is 2 mm. when the load is doubled - match the following (g = 9.8 m//s^2)

A load of 5kg hangs from one end of a vertical wire of length 1 m and of radius 1 mm. IF young's modulus of the material of the wire is 2 times 10^11 N.m^-2 , find the length of the wire when no load is acting on it.

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.
