Traditionally, these weights have been made of lead; it is estimated that up to 230 tonnes (500,000 lb) of lead, having fallen off car wheels, ended up in the environment. [8] According to the United States Environmental Protection Agency , these total more than 20,000 tonnes of lead worldwide every year, [ 9 ] and therefore the use of less ...
The unsprung mass (colloquially unsprung weight) of a vehicle is the mass of the suspension, wheels or tracks (as applicable), and other components directly connected to them. This contrasts with the sprung mass (or weight) supported by the suspension, which includes the body and other components within or attached to it.

The Federal Bridge Gross Weight Formula, also known as Bridge Formula B or the Federal Bridge Formula, is a mathematical formula in use in the United States by truck drivers and Department of Transportation (DOT) officials to determine the appropriate maximum gross weight for a commercial motor vehicle (CMV) based on axle number and spacing ...
A Scandinavian steelyard is a variant which consists of a bar with a fixed weight attached to one end, a movable pivot point, and an attachment point for the object to be weighed at the other end. Once the object to be weighed is attached to its end of the bar, the pivot point, which is frequently a loop at the end of a cord or chain, is moved ...
The system rotates without requiring the application of any external force or couple, other than that required to support its weight.

This is seen when a bicycle wheel gets a buckled rim.
