# A set of gears with fixed centers are connected in 2d as shown. the gear radii are r 1 = 8 m r1=8 m, r 2 = 8 m r2=8 m, r 3 = 6 m r3=6 m, and r 4 = 6 m r4=6 m, where the numbers correspond to the gear

A set of gears with fixed centers are connected in 2d as shown. the gear radii are r 1 = 8 m r1=8 m, r 2 = 8 m r2=8 m, r 3 = 6 m r3=6 m, and r 4 = 6 m r4=6 m, where the numbers correspond to the gear center numbers. point p p is attached to the gear at c 4 c4 and has acceleration magnitude a p = 27 m / s 2 ap=27 m/s2. the gear at c 3 c3 has angular acceleration magnitude α 3 = 2 r a d / s 2 α3=2 rad/s2 and the gear at c 2 c2 is rotating counterclockwise at a decreasing rate.
