When inter-joint bodies are manufactured with medium/acceptable accuracy, then the parts may assemble in only one particular position/orientation within the range of operation, but the mechanism will tend to squeal and jam when urged to depart from that point. These effects become aggravated under load due to the inevitable elastic deformation.

In Loaded Operation of Absolutely Accurate PartsShould the inter-joint bodies be manufactured with absolute accuracy, then the mobile assembly will function as anticipated, under no load, but the joints will suffer under load. Examples are some of the mechanical contrivances that prove to be of an unacceptably short service life, without an obvious reason.
