Tire balance is measured in factories and repair shops by two methods: with static balancers and with dynamic balancers. Tires with large unbalances are downgraded or rejected. When tires are fitted to wheels at the point of sale, they are measured again on a balancing machine , and correction weights are applied to counteract their combined ...
The Merrill Wheel-Balancing System was the world's first electronic dynamic wheel-balancing system. It was invented in 1945 by Marcellus Merrill at the Merrill Engineering Laboratories, 2390 South Tejon Street, Englewood, Colorado , and is now recorded on the list of IEEE Milestones in electronic engineering [ 1 ] and as an American Society of ...
FMC plant in South Charleston, West Virginia, 1970 FMC 210 Skidder made by FMC. In 1946, FMC bought Bolens Lawn and Garden Equipment. FMC changed its name again in 1948, becoming Food Machinery and Chemical Corporation. In 1961 the name was changed to FMC Corporation. In 1967, the FMC Corporation merged with the Link-Belt Company.
However a static balancer can only correct in one plane, so its accuracy is limited. A blade balancing machine attempts to balance a part in assembly, so minimal correction is required later on. Blade mass balancing is typically done for short blades, while long blades may require moment weighing in one or two axes.
In the case of a narrow wheel, balancing simply involves moving the center of gravity to the centre of rotation. For a system to be in complete balance both force and couple polygons should be close in order to prevent the effect of centrifugal force. It is important to design the machine parts wisely so that the unbalance is reduced up to the ...

Wheel alignment, which is sometimes referred to as breaking or tracking, is part of standard automobile maintenance that consists of adjusting the angles of wheels to the car manufacturer specifications. [1] The purpose of these adjustments is to reduce tire wear and to ensure that vehicle travel is straight and true (without "pulling" to one ...
