A force of 40N stretches a wire through 3cm,what force will stretch it through 5cm and through what length will a force of 100N stretch it? What assumption have you made?
Answered by bobpursley
if you assume a) that the elastic limit wont be met, and b) that is a linear elastic material, then
f=kx
40=k.03 or k= 1333N/m

5cm?
force=k*.05=1333*.05=67N

100=kx
x= 100/1333 = 7.5 cm
