QUESTION:

A \(\text { 4.0-m-long }\) steel wire has a cross-sectional area of \(0.050 \mathrm{~cm}^{2}\) Its proportional limit has a value of 0.0016 times its Young’s modulus (see Table 11.1). Its breaking stress has a value of 0.0065 times its Young’s modulus. The wire is fastened at its upper end and hangs vertically. (a) How great a weight can be hung from the wire without exceeding the proportional limit? (b) How much will the wire stretch under this load? (c) What is the maximum weight that the wire can support?
