On the Equilibrium of Planes

"On the Equilibrium of Planes" is a significant work by the ancient Greek mathematician Archimedes, focusing on the principles of leverage and balance. Although the text is primarily concerned with the equilibrium of planes (flat surfaces), it lays the groundwork for our understanding of mechanics and the behavior of objects under external forces. In this work, Archimedes discusses the conditions under which a planar object will remain in balance or equilibrium when subjected to various forces.
