Point Mass Analysis
Point Mass Analysis
In the point mass analysis, the only variable that required data from the actual pendulum was the distance from teh center of mass to the pivot point. This data was taken from Fusion360 using the 'property' feature, and and gave a distance of 6.82 centimeters from the pivot point to the center of mass. This was then put into the formula shown on the side. This was how the point mass analysis was taken for my pendulum, resulting in the value of 0.5238869158 seconds per oscillation.
Inertial Analysis
Inertial Analysis
The second method to find the oscillation frequency was to use inertial mass analysis. This was done using the masses and distances of each bolt from the pivot point. This distance of each bolt to the pivot point was gotten using Fusion360's dimension tool. The formula for inertial mass analysis was then used to find the time that it took for one oscillation, which result in being 0.5995293290415.
Two-dimensional Simulation Analysis
Two-dimensional Simulation Analysis
The WM2D simulation consisted of importing the AutoCad file into WM2D and retracing the shape to create a polygon in the same shape. If this was made of different parts, rigid joints would be used to join them. The density of the pendulum shapes was matched with that of the acrylic sheet used, and the mass of the bolts was matched with that in real life. The pendulum was then lifted to around 10 degrees and the program to run, with a graph made to measure the rotation of a part of the pendulum. However, the simulation didn't account for the measure of the escapement wheel or the friction between the pieces.
