A cable is cut into two equal parts. how will it affect the extension of the wire under same stretching force?

Answer 2

A cable is cut into two equal parts, the effect on the extension of the wire under the same stretching force will be the same.

• On cutting the cable into two equal parts, then the length of the cable will decrease. The area will remain the same.
• The Young's modulus of the wire will remain the same because it is the physical property of the material, and so by cutting it into half, the young's modulus will remain the same.
• The extension of the cable is independent of the length of the cable provided they are extended by the same stretching force.
• Therefore, the effect on the extension of the wire under the same stretching force will be the same.
