sTitle:The Comparison of Variables for Gear's Racing This study aimed to compare the variables used in gear's racing with the goal of identifying the most effective gear ratio for optimal performance. The variables analyzed included gear teeth, overall gear ratio, gear material, and gear shape. In order to gather data, a series of experiments were conducted using different gear combinations and a racing simulator. The results showed that gear teeth and overall gear ratio had the greatest impact on racing performance, with higher gear ratios and lar
