Lower gears give more torque for acceleration or climbing hills, while higher gears reduce torque to allow smoother, fuel-efficient cruisi

Invention on Instagram: "Automatic laser welding is a modern technique that uses a focused beam of light to melt and join metal with incredible precision. Unlike traditional welding methods that rely on electrical arcs or filler materials, laser welding directs concentrated energy to a very small area, which minimizes heat spread and distortion. This level of control makes it ideal for applications that demand accuracy and consistency, especially in complex designs and delicate components. One o
