PRACTICE / Elastic energy
Energy stored during gradual loading
A Hookean wire is stretched quasistatically from zero extension to 2 mm. The final tension is 80 N.
Find the stored elastic energy.
Organize the givens & assumptions
- Ffinal = 80 N
- ΔLfinal = 0.002 m
Quasistatic loading of a Hookean wire from zero tension; no hysteresis or plastic deformation.
- A
- B
- C
- D
