Choose the coefficient of friction wisely. Relevant information is given in the textbook. a. What is the maximum frictional force in the knee joint of a person who supports 70.0 kg of her mass on that knee? Fmax 686.7 XN 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.) Fmax = N
