Pneumatic or Pressure
Thrust
Pressure or Pneumatic Thrust, seen in a balloon, in ripe fruit and vegetables, eroded earth forms, sea creatures, the back of the human skull, the head of the femur, the egg, and all forms that are the result of tensions fairly evenly distributed. [Graham Collier writing of overt or kinetic energy in terms of thrust identifies Centripetal as one of three or four common manifestations.] These kinds of thrust are often seen in combination with elements of potential energy, as in a tent, a clothesline, or a suspension bridge, where the point thrust of pole or nylon is complemented by the catenary arc of the canvas, the line or the cables, or contrariwise in the association of continuous and discontinuous patterns in the formations of mountains.]
