1
Q
What is elastic strain energy?
A
the area under a force extension graph
2
Q
What has to be done to stretch a material or object ?
A
work , before reaching the limit of proportionality all work done is stored as elastic strain energy
3
Q
Equation for work done ?
A
W = 1/2 Fx where w = work done f = force x = externsion
