Painter on a Scaffold - Don't Fall Off!!

The video tutorial explains a physics problem involving a scaffold supported at two points. Using a meter stick model, the problem is to determine the closest point a 200g object can be placed on a 93g meter stick without losing balance. The tutorial covers the creation of a free body diagram, summing forces and torques, and understanding rotational equilibrium. It also discusses the role of normal forces and how they change as the object moves. The solution is calculated, showing the object can be placed 6.0 cm from the end of the meter stick before it becomes unbalanced.
