Objectives

The clock project is a project in which I was tasked to design a pendulum clock, which consisted of an escapement wheel and unique pendulum design. This introduced us to the use of physics in the form of inertia, motion, and energy, along with subjects like speed, position, velocity, acceleration, and their respective equations. We then applied these concepts to our clocks to find the oscillation frequency using point mass analysis, inertial analysis, and a software analysis.

In addition to using physics to understand why the clock works the way it does, we used Fusion 360 to CAD the escapement wheel and pendulum, with the pendulum having etching to create patterns on the surface. The Fusion 360 file was then imported into AutoCad, which was used to compile the sketches into files that the Lasercamm could cut out. I found the most challenging part to be using the Fusion 360 to create the wheel and pendulum because I was unfamiliar with the tools and different selections I could make.

Outcomes

The clock ended up having an oscillation frequency of about 0.6120 seconds, which had an error of 3.46%. The types of analysis from least to most accurate are point mass, Working Model 2D, inertial mass analysis. The inertial mass analysis was the most accurate of the three prediction methods used. The inertial mass analysis likely had the most accurate reading because it took into account the location and weight of the bolts and what affect this had on the oscillation of the pendulum.
