How do buildings stand still? In this lecture, Prof. Walter Lewin explores the physics of balance. We define the two critical conditions for Static Equilibrium: net force and net torque must both be zero. Through rigorous problem-solving and demonstrations, we learn how to analyze structures like ladders and beams to ensure they remain perfectly stationary.
