SUMMARY
The maximum load that can be supported by a copper wire with a diameter of 0.37 mm is calculated using the breaking stress of copper, which is approximately 3.00×108 N/m2. The cross-sectional area of the wire is determined using the formula for the area of a circle, A = π(d/2)2. When 17 percent of this maximum load is applied, the wire will stretch by a fraction that can be calculated using the relationship between stress, strain, and Young's modulus for copper.
