WebCalculate the elastic potential energy which will be stored in this spring once it has been extended. Step 1: Find the extension e = 0.08 - 0.02 = 0.055m Step 2: Calculate the spring constant F = ke k = F/e k = 3 / 0.055 = 54.5N/m Step 3: Plug this into the elastic energy formula. Ee = 0.5 x 54.5 x 0.0552 = 0.0824J Force and Extension 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

WebThe force-extension graph. A force-extension graph can be used to calculate the work done in joules when stretching a spring. Force should be plotted on the vertical (y) axis. Extension should be plotted on the horizontal (x) axis. As long as the limit of proportionality is not exceeded this should produce a straight line graph that passes ... WebBelow the elastic limit, the material exhibits elastic behaviour. Above the elastic limit, the material exhibits plastic behaviour. Elastic deformation occurs in the ‘elastic region’ of the graph. The extension is proportional to the force applied to the material (straight line) Plastic deformation occurs in the ‘plastic region’ of the ...
