WebThe equation is the area of a right-angled triangle under the force-extension graph Where: E = elastic strain energy (or work done) (J) F = average force (N) Δ L = extension (m) Since Hooke's Law states that F = kΔL, the elastic strain energy can also be written as: Where: k = spring constant (N m –1) Breaking Stress WebIt turns out the area underneath any force versus position graph is gonna equal the work, not just ones where the force is constant, even where the force is varying, if you …
