Wheel balancing |
When a body with a mass rotates about an axis, it produces centrifugal force, This force is directly proportional to the mass and the radius of rotaion of the mass and is directly proportional to the square of the speed of revolution of the mass.
This force occurs in every tyre, which has a mass of its own, but the entire mass is concentrated at a point. Thsi mass is effectively that mass which is not balanced by the same mass on the other side.
Wheel balancing is aimed at evening out the masses on all planes. This is done by adding masses on either side of the tyre. These get calculated at a specific speed and the masses added neutalise the force and couple vectors created by the unbalanced mass on the tyre by the force and couple vectors of their own, by acting in equal but opposite direction.
This helps in keeping the tyre free of any unbalance and results in the action of constant and unfiorm forces on the tyre. This will help the constant wear rate of the tire and also reduce the effect of unbalanced forces on the wheel bearings, thus increasing their life.
Don't forget to balance all four wheels at regular intervals to guarentee a long tyre and bearing life for your car. |
