Question

mechanical properties of solid numerical

Answer 1

The extension of the rod is approximately $6.37\, \text{mm}$.

Answer 2

1. Compute cross-sectional area $A = \pi (0.01)^2$.

2. Use extension formula $\Delta L = \frac{FL}{AE}$.

3. Substitute values and simplify to get $\Delta L \approx 6.37\, \text{mm}$.
