ABSTRACT
The use of linkages may be found in many walks of life. An example in the home is of the rear suspension on a mountain bike. In the building industry, a further example will be of the hydraulically operated buckets tted to wheeled loaders; in the aerospace industry, extensive use of linkages is found for extending and retracting the aircraft landing gear units including wing aps and so on. In the automotive industry, the vehicle suspension systems rely heavily on the use of linkages for maintaining road wheel positions.
