phet.mp4Step 1. Go to the Phet Simulation Link Below.
Step 2. Select the Balance Lab
Step 3. Set the bottom toggle to be a free lever with the fulcrum in the middle (choose the one on the bottom right).
Step 4. Set the right side of the lever to have a 10kg weight at 6 units from the end; and a 15kg weight at 4 units from the end.
Step 5. Find where to place a 20kg & 5kg mass on the left side so that the beam is balanced horizontal.
