PIRA 1J40.50 - Static Torque: Roberval Balance
Instructions / Notes:
- When the lever arms are screwed into the middle of the sides of the parallelogram, the parallelogram balance maintains a neutral equilibrium no matter where the weights are positioned on the lever arms.
- When the lever arms are screwed into the top of the sides of the parallelogram, the demo becomes a normal single lever balance.
