By how much will a 3.0 m long copper wire elongate if a weight of 10 kg is suspended from the lower end with the upper end keeping fixed? The diameter of the wire is 0.4 mm. Given: Y for copper `=10^(11)Nm^(-2)` and `g=9.8ms^(-2)`

A weight of 1.0 kg is suspended form the lower end of a wire of cross- section 10 mm^(2) . What is the magnitude and direction of stress produced in it ? Take g= 9.8 ms^(-2) .

What mass must suspended from the free end of a steel wire of length 2m and diameter 1mm to stretch it by 1mm ? (Y=2xx10^(11)Nm^(-2))

What should be the weight suspended from the end of a steel wire 2 m in length and w mm in diameter to increase the length by 1 mm ? (Y=19xx10^(11)N//m^(2))

When a weight of 5 kg is suspended from a copper wire of length 30 m and diameter 0.5 mm , the length of the wire increases by 2.4 cm . If the diameter is doubled, the extension produced is

A copper wire and a steel wire of same length and same cross-section are joined end to end. The compositive wire is hung from a rigid support and a load is suspended form the free end. The increase in length of the compositive wire is 4 mm. The increase in copper wire will be (Y_(copper)=1.2xx10^(11)N//m^(2),Y_(steel)=2xx10^(11)N//m^(2))

A 5 metre long wire is fixed to the ceiling. A weight of 10kg is hung at the lower end and is 1metre above the floor. The wire was elongated by 1mm . The energy stored in the wire duw to streching is
