# Explanation of the working principle of okiagari-koboshi

Extracts from this document...

Introduction

Explanation of the working principle of model (okiagari-koboshi)

• Principle One: Centre of gravity

Since the okiagari-koboshi is a self-righting doll and would not topple over, the centre of gravity has to be as low as possible in the model. According to the concepts of centre of gravity, to make an object have a lower centre of gravity, the object has to have a heavier base and have a larger base area. Thus, these concepts were implemented into the process of making the model. It has a heavy base in comparison to the model’s body, and has a large base area.

• Principle Two: Stability

One of the key properties

Middle

• Principle three: Turning effects of forces

As explained earlier, the okiagari-koboshi needs to maintain a stable equilibrium for it to work. In a stable equilibrium, the object returns back into its equilibrium position after being pushed. This is due to the turning effects of forces, also known as moments. When the okiagari-koboshi is tilted to one side, the centre of

Conclusion

Conclusion

To make the okiagari-koboshi with it being functional, there are two key factors to consider when making it: 1. it must have a heavy base heavier than its body, and 2. it must have a large base area bigger than its body.
