Abstract

This study investigates the influence of spring pitch on energy storage capacity by analyzing the behavior of a spring-loaded Tamiya car system impacted by a cue ball rolling down an inclined plane. Springs with varying pitches were tested to analyze the relationship between their geometric characteristics and the mechanical energy stored during impact. Using principles of energy conservation, momentum, and restitution, the experiment calculated the spring constant, compression distance, and corresponding energy output. Results indicated that larger pitch distances generally yielded higher spring constants and energy storage, leading to greater displacement of the Tamiya car. Data showed that spring’s ability to absorb and convert kinetic energy is significantly influenced by its stiffness, which is affected by pitch and number of active coils. The study validates theoretical models with experimental outcomes and supports the hypothesis that spring geometry directly impacts energy efficiency. These findings contribute to optimizing spring design for energy storage applications, particularly in mechanical and sustainable energy systems where energy transfer and compact mechanical design are critical.
