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

The length of a wire is 4m . Its length is increased by 2mm when a force acts on it. The strain is

A copper wire of length 3m and diameter 1mm is stretched to increase its length by 0.3cm. What is the lateral contraction, if the Poisson's ratio for copper is 0.25?

A load of 3kg produces an extension of 1.5 mm in a wire of length 3m and diameter 2mm . Young's modulus of the material of the wire is

The resistance of a copper wire of length 5 m is 0.5 Omega. If the diameter of the wire is 0.05 cm, determine its specific resistance.
