Unformatted text preview: Slope Angles for Mass Movements Slope angle (α) is measured as degrees from an imaginary horizontal reference line. In this part of the exercise, you will conduct experiments to determine the critical (minimum) slope angle for initiating the movement of a particle on one planar surface. The “slope” will be a clipboard and the slope materials will be referred to as Mass A and Mass B. You will be experimenting with a static condition; in other words, the mass will be at rest on the slope when the experiment begins and the critical angle will be that at which movement begins. Because it is difficult to know the exact angle at which movement begins, you will do the experiment 10 times and average the results. As you do these experiments, remember that the experimental...
