A parabola is the curve when you section a cone, and the curve formed by the cable on a suspension bridge...however when the bridge is being constructed the cable is in the shape of a catenary curve.
A catenary curve being the curve if you stretch out a length of chain horizontally and allow it to sag in the centre.
A bit off topic there! Interesting though!
