For this lab, I observed the station with the two ramps. The setup consisted of two ramps with a spinning wheel on the higher side of each, a string with one side tied to the cart or block, and the other side attached to a spring scale with weights on the non-spring side. Both ramps were sitting at about 10 degree angles. In order to keep the cart stationary, I had to adjust the weights on the spring scale. By doing this, I was making the Fnet = 0. The forces acting on the cart and block were, gravitational force, normal force, and frictional force.
The FBD for the block can be seen here
