Structure+and+Stability

Structures and Stability. We will be studying the following topics. There will be notes and assigments for each topic. Please make sure your notes and assignments are in order.

An object will balance if the centre of gravity is above or below a supporting structure. You created a device that would balance, there are a few examples below.
 * 1) What is the centre Gravity?
 * It is the point where gravity will pull on a object. Gravity only pulls on the centre of gravity. We did many activities in class to prove this. Lance can't lift a chair, nose dive, straight up stand up to name a few.
 * 1) How do objects balance?

The nose dive. The reason why some people can do it and others can't is because the centre of gravity is higher on the people who can't do it. When they bend over to reach the paper with their nose, the centre of gravity passes by the support (knee). They will then fall over. Those with a lower center of gravity will not fall over because their centre of gravity does not pass the support (knee).

Different ways to Stabilize objects. You have notes on this topic in your note book.

 * 1) Types of Forces
 * Shear- Rifping force
 * Tension - Pulling force
 * Torsion - Twisting force
 * Compression- compression force
 * 1) What shape is the Strongest?
 * Big Building Assignment
 * We found out that the triangle was the strongest because is able to spread the weight out better than the rectangle and dome.
 * 1) Build a bridge out of popsicle sticks.
