1J40.50 - Roverbal Balance
Demonstrate a Roverbal Balance
Obtain the Roverbal Balance. The base and stand are together but seperate. Stick the stand into the woodbase.
Unfold the platforms and place equal masses on the platforms. To show how a roverbal balance only measures imbalances, remove one mass from one of the platforms or add an extra mass to one of the platforms.
A roverbal balance measures equal wieghts only. Any imbalance results in immediate displacement of the platforms. Many street goods, like spices for example, are weighed out this way by balancing a known weight on a roverbal balance.
