Creating the Mechanisms:

After selecting my to mechanisms the "golden section" and the "linkwork flexible-link mechanism of a pan-type balance" (images above) I exsplored the two through the process of drafting and constructing a sketch model I was able to fully understand how the two worked. When constructing my sketch model I was able to use the process of elimination to figure out how to draw the "golden scetion" by using the mechanism to creat it. At first I thought the two main arms were fixed along the horizontal line but after further examination I realized that in actual fact only the center arm was fixed and the other one was positioned parellel to it on the outer side of a moving wheel. Through the combination of fixed and semi-fixed arms on the roting wheel I was able to draw the "golden section".

The second mechanism the "linkwork flexible-link mechanism of a pan-type balance" however was much easier to understand. Just by looking at the drawing I was abel to see how it works and there move on to constructing the two out of strathmore (ya!).
