Turning radius
From Wikipedia, the free encyclopedia
The turning radius or turning circle of a vehicle is the radius of the smallest circular turn (ie. U-turn) that the vehicle is capable of making. It is often used as a generalized term rather than a numerical figure. For example, a vehicle with a very small turning radius may be described as having a "tight turning radius".
A notable exception is in this description is of vehicles that are capable of spinning around their central axis, such as a tank or certain lawnmowers as they do not form a circular path as they turn. In this case the vehicle is referred to as a "zero turning radius" vehicle, although whether or not the turning radius is actually nonexistent is unclear.
Some camera dollys used in the film industry have a "round" mode which allows them to spin around their z axis by allowing synchronized inverse rotation of their front and rear wheel sets, effectively giving them "zero" turning radius.
Turning circle is sometimes measured as the diameter of the minimum turn rather than the radius.
