Physic Question: Measure weight, increase platform weight

Possible we increase platform (body with property ‘static’)
For example, there is a floating platform (‘static’), if 2 body stack on it, it will not drop, but if >5 boxes (physic body) stack on top, it will drop
how can we simulate it via corona?

steelyard or scale machine simulation?
i stuck when try to simulate a scale
