This physics image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}. It is recommended to name the SVG file “Kneehingeleverage.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.

This physics image was uploaded in the JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the PNG or SVG format. If possible, please upload a PNG or SVG version of this image without compression artifacts, derived from a non-JPEG source (or with existing artifacts removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans. If this image is a diagram or other image suitable for vectorisation, please tag this image with {{Convert to SVG}} instead of {{BadJPEG}}. If not suitable for vectorisation, use {{Convert to PNG}}. For more information, see {{BadJPEG}}.

This is an example of a mechanical advantage in a mechanism: in its application a relatively small input force 'V' is translated into a relatively large output force 'H'. The mechanism looks like the straightening of a leg with the knee equivalent to the hinge. I have made this sketch myself. I hope it helps illustrate a very basic mechanical engineering principle.
