let the tension in the wire
Young modulus = stress/strain
2 *10^11 = (T/(pi * (0.30/2 *10^-2)^2))/(0.0020/1.50)
2 *10^11 * (0.0020/1.50)= (T/(pi * (0.30/2 *10^-2)^2))
solving for T
T = 1885 N
the tension in the cable is 1885 N

A piano wire 0.70 m long and 0.70 mm in diameter is fixed on one end. The other end is wrapped around a tuning peg 4.5 mm in diameter. Initially the wire, whose Young's modulus is 2.4× 10 10 N/ m 2 , has a tension of 20 N . Find the tension in the wire after the tuning peg has been turned through one complete revolution.
