Levers

The video explains levers, a type of simple machine, and their components: the lever itself and the fulcrum or pivot. It describes how levers allow movement of a load with effort around the fulcrum, and how the fulcrum's position affects the effort needed. Examples include a spanner, where the nut is the load and the spanner head is the fulcrum, and a door, where the hinge is the fulcrum. The video highlights the importance of the fulcrum's position in minimizing effort.
