 Node a1 is the node that is undergoing circular motion. With no oscillation, the angular displacement of node a1 will be increasing as shown in the first graph in the figure below.

 ** For Node b1 **
+\\
+Node b1 oscillates as the crank moves. As shown by the angular displacement graph, the angular displacement of node b1 comes in cycles, where the maximum displacement is roughtly -15 degrees (which is 15 degrees counterclockwise).
+\\
+Both the angular velocity and angular acceleration oscillates as well as the bar changes direction of rotation.

+The cyclic nature of the motion are all captured by the data and the filtered data. However, similar to the data obtained from Solidworks, the extrema of the velocity and acceleration data all have lower extremas compared to the theoretical MATLAB data.
+\\
+To compensate for this error in real life, the motor speed that is used to drive the 4-bar mechanism can be increased to increase the tangential velocity, tangential acceleration, and normal acceleration.
