Note that the end result rotational velocity may differ from the input due to compliance in the joints. Stiffer compliance can cause more accurate tracking, but higher internal torques and vibrations.
The metal-bis(terpyridyl) core has rigid, conjugated linkers of para-acetyl-mercapto phenylacetylene to determine electric contact in a two-terminal configuration using Au electrodes. The structure of the [Ru(II)(L)(2)](PF(6))(2) molecule is determined using single-crystal X-ray crystallography, which yields good agreement with calculations predicated on density functional theory (DFT). By way of the mechanically controllable break-junction strategy, current-voltage (I-V), characteristics of [Ru(II)(L)(2)](PF(6))(2) are acquired on a single-molecule level under ultra-huge vacuum (UHV) circumstances at various temperature ranges. These results are in comparison to ab initio transportation calculations predicated on DFT. The simulations display that the cardan-joint structural component of the molecule regulates the magnitude of the current. Furthermore, the fluctuations in the cardan angle keep the positions of guidelines in the I-V curve generally invariant. As a result, the experimental I-V characteristics exhibit lowest-unoccupied-molecular-orbit-centered conductance peaks at particular voltages, which are also found to always be temperature independent.

In the second technique, the axes of the input and output shafts are offset by a specified angle. The angle of every universal joint is normally half of the angular offset of the source and output axes.

consists of a sphere and seal set set up of the same design and performance since the well known MIB offshore soft Cardan Joint seated valves. With three moving components the unit can align with any tensile or bending load put on the hose. Thus minimizing the MBR and loads used in the hose or linked components.
This example shows two methods to create a regular rotational velocity output using universal joints. In the 1st method, the position of the universal joints is exactly opposite. The result shaft axis is parallel to the input shaft axis, but offset by some distance.

Multiple joints works extremely well to make a multi-articulated system.
