"An 80 kg person jumps off a bridge with a bungee cord of unstressed length 100 meters and a cross sectional area of 400 mm squared. Assume cord has zero weight, how far into the gorge does Bob plunge and what is the maximum force in the cord? The cord has a modulus of Elasticity E = 8 MPa."
The furthest I can get with this question is solving for mg = kx at the equilibrium point, and the distance from that point to the unstretched 100 meters is around 124 meters. How do I carry forward is beyond me. Can someone please explain to me how I can solve for the distance from the equilibrium point to the bottom of the plunge?
Thanks for your time.
