What is the maximum frictional force in the knee joint of a person who supports 66.0 kg of her mass on that knee? (b) during strenuous exercise it is possible to exert forces to the joints that are easily ten times greater than the weight being supported. what is the maximum force of friction under such conditions? the frictional forces in joints are relatively small in all circumstances except when the joints deteriorate, such as from injury or arthritis. increased frictional forces can cause further damage and pain

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?
