Scetch on Simon Stevin  tombstone

When the object 1N is moving up the inclined level, gains 3x1 joule gravitational energy.
In the same time P is moving down and loses Px5 gravitational energy. Thus 3x1=Px5, and
P=3/5 Newton.  

Feynman characterize it as a genius idea to estimate the strength  of the force P using the conservation of energy.
