 The `world` [Object3D](@ref) has feature [Scene](@ref) and is therefore the inertial system. The `body` Object3D is a [Solid](@ref) and defines the pendulum as a mass point with `mass = 1.0`. The `bodyFrame` Object3D defines a coordinate system on the `body` that is translated along the x-axis. A revolute joint connects `world` with `bodyFrame`.
