Mechanical Moments and the concept of "Summing of Moments"

This video discusses the basic concept of mechanical moments. Theoretical calculations and physical experiments are used to provide insights on a classical "statics" problem where clockwise moments generated by hanging weights are counterbalanced by a counterclockwise moment generated by a scale. The concept of "summing of moments" is used to predict the force generated by the scale to maintain a static (non-moving) system. This video is intended for students in basic physics or statics classes.
