LOAD VS. ELONGATION OF RIGGING LINES
The load vs. elongation curves of two
ropes with similar breaking strengths.
The shaded area beneath each of the curves
represents the energy absorbed as the

rope stretches. The two areas shown are
equal representations of the same energy
absorption or the catching of the same
falling load. As shown, Nystron absorbs the
energy while reaching the lowest load,
but stretching the farthest.
