Amphibious structure prototype
From my prototype model is the experiment of contrasting weight of the 2 objects and the relationship when the structure is growing up between vertical and horizontal. By a heavy object act as an anchor while the light one floating according the tide. So by the nature of the structure that could be flexible, I found the similar idea on "scale instruments " based on what is the things to be weight and does it need to be counter weight in the same time.
These instruments I categorized into 2 main different of an equal arm beam balances and unequal arm beam balances.
From this drawing portray the different approach by each types totally have a distinguish on how to calibrate , the capacity of the instrument and how accurate it can be. which i think this research could help to develop the idea further.
