How great a weight can be hung from the wire without, Ask an Expert

Academics

A steel wire has the following properties:

Length = 5.00 m
Cross-sectional area = 0.040 cm^2
Young's modulus = 2.0 * 10^11 Pa
Shear modulus = 0.84 * 10^11 Pa
Proportional limit = 3.6 * 10^8 Pa
Breaking stress = 11.0 * 10^8 Pa

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 does the wire stretch under this load?
C)What is the maximum weight that can be supported?
