maximum loss of PE= 0.5* Pfail *
E=Youngs Modulus, =stress, =strain
height above initial position:
Yield strength / yield point - the stress at which a material begins to deform plastically.
Prior to the yield point the material will deform elastically and will return to its original
shape when the applied stress is removed. Once the yield point is pas
