How are parabolas used in real life?
When liquid is rotated, the forces of gravity result in the liquid forming a parabola-like shape.
The most common example is when you stir up orange juice in a glass by rotating it round its axis.
Parabolas are also used in satellite dishes to help reflect signals that then go to a receiver.

Why is a parabola a strong shape?
The parabola is considered such a strong shape because of its natural oval shape. Both ends are mounted in a fixed bearing while the arch has a uniformly distributed load. When an arch carries only its own weight, the best shape is a catenary.
Are arches parabolas?
