org.jbox2d.dynamics.joints.GearJointDef
public class GearJointDef
Gear joint definition. This definition requires two existing
revolute or prismatic joints (any combination will work).
The provided joints must attach a dynamic body to a static body.
A gear joint is used to connect two joints together. Either joint
can be a revolute or prismatic joint. You specify a gear ratio
to bind the motions together:
coordinate1 + ratio * coordinate2 = constant
The ratio can be negative or positive. If one joint is a revolute joint
and the other joint is a prismatic joint, then the ratio will have units
of length or units of 1/length.
Warning: The revolute and prismatic joints must be attached to
fixed bodies (which must be body1 on those joints).
