Ever wondered why some gears spin fast while others turn slowly but with more force? It all comes down to gear ratios — the relationship between the number of teeth on two meshing gears. 🔍 Here’s the basics: Gear Ratio = (Number of teeth on driven gear) ÷ (Number of teeth on driving gear) A higher ratio = more torque, less speed A lower ratio = more speed, less torque 💡 What this means in real-world applications: Need power for heavy loads? → Bigger driven gear = higher ratio Need speed and ef
