Introduction & Objectives
My name is Rhea and I'm part of Cluster 2: Engineering Design and Control of Kinetic Sculptures. Our first project will be making a Clock Inspired Pendulum. Through this project, I hope to gain valuable hands-on experience in mechanical engineering, develop my lab skills, and deepen my understanding of 3D modeling and LaserCAMM software. As an aspiring aerospace engineer, I believe this project will help lay the groundwork for future coursework in Mechanical and Aerospace Engineering (MAE) by giving me a strong foundation in design, precision, and engineering principles.

Our Clock Pendulum project provided key insights into the principles of mechanical motion, system dynamics, and the design process. Using Working Model 2D, we created a simulation of our pendulum’s motion, predicting its behavior under specific conditions. This allowed us to refine our design before moving to fabrication.
Once the physical model was constructed using LaserCAMM and 3D design software, we compared its motion to our simulation. The side-by-side comparison (see below) highlighted both the strengths and limitations of our modeling assumptions. While the simulation predicted a nearly perfect harmonic motion, the actual clock experienced small deviations due to friction, slight imbalances in weight distribution, and material stiffness.

The completed pendulum ticks at a steady rate, as shown in the video. Its oscillation time closely matches my simulation, confirming the accuracy of my calculations and validating the overall design.
