How Do Centrifugal Clutches Work?

How does a centrifugal clutch work? What is a centrifugal clutch? Centrifugal clutches are used in go karts, mopeds, chain saws, lawn mowers, and many other small engine powered devices. They work by using the principle of centrifugal force to have a clutch shoe apply a friction pad against the clutch housing, thus rotating a device which requires torque to run. At idle speed, springs hold the clutch shoes in so that there is no torque transfer to the clutch housing.

Understeer Vs Oversteer - Explained

What is the difference between understeer and oversteer? What causes understeer and oversteer? How can you reduce understeer? How can you reduce oversteer? This video looks into both steering situations, and relates them to slip angles. A car with a larger front slip angle than rear slip angle will understeer. A car with a smaller front slip angle than rear slip angle will oversteer. This can be altered by changing many things, including downforce, camber, toe, tire compound, tire pressure, width, suspension geometry, spring rates, etc.

Slip Angles - Tire Traction - Explained

What is a slip angle? How do slip angles relate to understeer and oversteer? A slip angle is the angle between the direction the wheel is pointing and the direction the tire contact patch is traveling. This is a result of the elastic properties of rubber, which deform under friction. The slip angles of the front and rear tires dictate whether or not the car is understeering or oversteering, and they also influence lateral grip as slip angle is related to the coefficient of friction of the tire.

Professional YouTuber - Earn Money From Your Home!

As a professional YouTuber, I treat my precious work hours with the utmost devotion. Making cash on the internet isn't for everyone, because apparently it alters your physical appearance as quickly as being president does. Regardless, lets have a look through a typical Monday morning as the brains behind Engineering Explained. Most of my work is obviously just contracted out.
