Maximum Area Triangle
A force proportional to the length of each side are applied to the side's midpoint. This models a constant pressure, and potential energy should be minimized when area is maximized. Press Show to see the tangents to the curve at the points of contact. What do you notice? You can change the definition of the curves, but be careful, or the masses might escape!
Maximum Perimeter Triangle
Constant force actuators push outwards. As the potential energy in each actuator is equal to its length, this machine should settle where the triangle's perimeter is maximum. Press Show to see the reflections in the tangents of a beam of light transmitted along one edge of the triangle.
