**Static Equilibrium by: Jay Fred**
Today, September 30 2008, every student either worked on the original Static Equilibrium Lab or the post lab. In the Post lab, you had to notice and record what effects Burl's weight has as he walks across a ruler. There are three scales: **1)** Scale 1 **2)** Scale 2 **3)** Scale 1 + 2. The slope in Scale 1 shows, as you increase the position on the ruler, the amount of force will decrease. Now for Scale 2, as you increase the position on the ruler, the amount of force also increases. But in Scale 3, The position on th ruler is still increasing but the amount of force is constant thoughout the whole Scale.

On the original Static Eqlibrium lab the goal was to find the scale readings of different weight placements and different position of spring scales. As we went through this lab, we found out what happens if Burl the painter is on the left, middle, or right side of the ruler. Also graphing data on Burl's position and the force on the scale improved our understanding of the idea. For my group, the y-intercept is 11.06 newtons and the slope was 0.3746 cm.
