Kinetic Chain - Physiopedia
The kinetic chain (sometimes called the kinematic chain) is an engineering concept used to describe human movement. It is used in a wide variety of clinical conditions, including musculoskeletal, sports medicine, neuro-rehabilitation as well as prosthetics and orthotics. The concept was introduced by Franz Reuleaux, a mechanical engineer, in 1875.
Kinematic chain mechanism inversion_grashoff
3 KINEMATIC CHAIN: Kinematic chain may be defined as a combination of kinematic pairs, joined in such a way that each link forms a part of two pairs and the relative motion between the links or elements is completely or successfully constrained. For example, the crankshaft of an engine forms a kinematic pair with the bearings which are fixed in ...

Kinematic and Dynamic Analysis Overview
Kinematic analysis is a simpler task than dynamic analysis and is adequate for many applications involving moving parts. Kinematic simulations show the physical positions of all the parts in an assembly with respect to the time as it goes through a cycle. This technology is useful for simulating steady-state motion (with no acceleration), as ...

The mill is put into rotation by the wheel B, driven by the hydraulic power of the water of a river. A kinematic chain, made of the gears C, E, F, G brings the motion to the wheel H, which puts into rotation the central shaft I of the ghirlanda. The central shaft has eight spokes fixed at different levels and resting on wooden circles.
