Select the correct answer.The change in length of a steel wire under an applied load can be halved by keeping all other conditions constant but using:
A. A different material having a Young's modulus half that of steel
B half the cross sectional area of the steel wire
C half the length of steel wire
D half the radius of the steel wire
