(a) 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 10 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.

A block of mass mį = 4.00 kg is put on top of a block of mass mp = 7.00 kg. To cause the top block to slip on the bottom one while the bottom one is held fixed, a horizontal force of at least 15.0 N must be applied to the top block. The assembly of blocks is now placed %3D on a horizontal, frictionless table (see the figure). Find the magnitudes of (a) the maximum horizontal force F that can be applied to the lower block so that the blocks will move together and (b) the resulting acceleration of the blocks.

The figure shows a section of a cable-car system. The maximum permissible mass of each car with occupants is 2200 kg. The cars, riding on a support cable, are pulled by a second cable attached to the support tower on each car. Assume that the cables are taut and inclined at angle 0 = 39º. What is the difference in tension between adjacent sections of pull cable if the cars are at the maximum permissible mass and are being accelerated up the incline at 0.85 m/s²?
