Pulleys and Tension in static equilibrium Summary

This video tutorial explains the concept of pulleys and tension in static equilibrium. It begins by introducing the setup of a pulley system with a rope and mass, and outlines the assumptions needed to prove that tension is constant throughout the rope. The video then uses a free-body diagram to illustrate the forces at play, demonstrating that tension is uniform across the system. The tutorial concludes by emphasizing the key takeaway that tension remains consistent in a static equilibrium scenario.

What does a free-body diagram of a pulley illustrate?

Why is it stated that the tension is uniform everywhere in the rope?
