Answer Posted / guest
A counterweight is often used in traction lifts
(elevators), cranes and funfair rides. In these
applications, the expected load multiplied by the distance
that load will be spaced from the central support (called
the "tipping point") must be equal to the counterweight's
mass times its distance from the tipping point in order to
prevent over-balancing either side. This distance times
mass is called the load moment.[2]
