A planetary gear system also known as an Epicyclic gearing or planetary gearing consists of spur gears arranged in an epicyclic configuration. In this setup, a central gear, known as the sun gear, acts as the input and drives the system. Multiple “driven” gears, or planets, orbiting the sun gear within a gearbox. These planets mesh with…
What’s the difference between energy vs power? In the realm of physics and engineering, the concepts of energy and power are fundamental but often misunderstood. While they are closely related, they represent distinct aspects of physical systems. Energy is the ability to do work, while power is the rate at which work is done or…
Have you ever wondered how an automotive suspension system is designed? From ATVs (all-terrain vehicles) to locomotives to modern passenger automobiles most types of vehicles that move people from one place to another rely on a suspension system to improve ride quality and comfort. There are a few common types of automotive suspension systems such…
