Wheel nuts are used to secure the wheel to the vehicle, and wheel nuts need to be loosened and eventually removed any time you want to change a tire, access the brakes, and do a variety of other repairs on your vehicle.

A rocker arm is a valvetrain component in internal combustion engines. Rocker arms were first invented in the 19th century and have changed little in function since then. Improvements of rocker arms have been made, however, in both efficiency of operation and construction materials. Many modern rocker arms are made from stamped steel, though some applications can make use of heavier duty materials.

A dry clutch is one with a plate outside the engine casing. Dry clutch uses friction to engage and has no need for lubricant. Due to the increased friction, dry clutch tends to overheat quickly. To counter the problem, dry clutch has a large surface area to allow for optimal air cooling. Because dry clutch is not awash with oil, dry clutches deliver increased power to the rear wheel and less drag to the engine.

How does CO₂ laser cutting work?The CO₂ laser is one of the earliest gas lasers. Developed by Kumar Patel in 1964, it is still one of the most useful lasers today. With its high power and levels of control, CO₂ lasers can be used for applications requiring precision, mass production, and most import
