Artificial joints, as well as natural joints, basically use the same method as all sorts of machinery does, namely, lubrication.
efficency is reduced by friction.
1. There is a thick liquid produced in the joint spaces to cushion and reduce friction. This viscous fluid is called synovial fluid.For additional information see related links.
Cartilage in joints REDUCE friction.
when we polish surfaces, the molecules or atoms of surface come closer to each other so there is no space for fiction so it is reduced but not reduced to zerowe cant reduce friction to zeroWhen we polish a rough surface smoothly,the unequalities gets reduced,therefore friction is reduced
Friction can be reduced by using lubricants like oil or grease on surfaces. To increase friction, surfaces can be roughened or materials with higher coefficients of friction can be used. Adjusting the weight or pressure between the surfaces can also increase friction.
Lubricating fluids like synovial fluid in the joint help reduce friction by providing a smooth surface for bones to glide against each other. Additionally, the cartilage covering the ends of bones acts as a cushion, reducing friction during movement. Strengthening the muscles around the joint can also help stabilize and support it, reducing friction.

With aerodynamics.
I believe that the most effective and common way to inspect a friction weld is by ultrasound.
Lubrication and ball bearings both reduce friction.
Because the joints of the bone that Cary the weight are not functioning as well as they should. Therefore by reducing the load on joints further damage is reduced and the amount of pain caused by already damaged joints is also reduced.
Water is as far as it goes.
