Swara uses a broom to sweep the floor. Her top hand holds the end of the handle steady while her lower hand pushes the handle back and forth. Where are the Fulcrum (F), Effort (E), and Load (L) located for the broom?
  1. F at top, E in middle, L at bottom
  2. L at top, F in middle, E at bottom
  3. E at top, L in middle, F at bottom
  4. F at top, L in middle, E at bottom

Solution

The steady top hand acts as the fulcrum (pivot), the middle hand applies effort, and the broom head pushing dust at the bottom acts as the load, making it a Class III lever.
