A 3.6 meter long steel wire has a cross-section area of 0.047 cm2. Its proportional limit has a value of 0.0015 times its Young's modulus. Its breaking stress has a value of 0.0069 times its Young's modulus. The wire is fastened at its upper end and hangs vertically.
(a) Find how great a weight can be hung from the wire without exceeding the proportional limit?
N
(b) Find how much will the wire stretch under this load?
mm
(c) Obtain the maximum weight that the wire can support?
