Station 4

For Station 4, a mass hung motionless from two spring scales supporting it from each side. It was connected to the cabinet. The spring scales read 3.7 and 3.8 N. After drawing a free body diagram and adding the vectors together, it created a triangle. With the S.S forces pointing NE and NW, the gravitational force was drawn south to close the figure with about 4.3 N. This made since because the mass was still causing the net force to be 0 N. I noticed that the mass actually was 3.7 N when measured, but on the FBD it was 4.3 N. This was fine though because I was close. Fractions of an angle difference could cause this, so it was fairly accurate.
