The lubrication of bone joints is a subject of ongoing medical research. Two bones connected at a joint do not touch. The bones are covered in articular cartilage, and are surrounded by lubricating synovial fluid. Rheumatoid arthritis results in overproduction of synovial fluid, swollen joints, and difficult and painful movement. Other joint disorders degrade the synovial fluid, directly increasing the friction between the bones, resulting in painful motion.
- The horizontal force F⃗h would rotate the femur head clockwise in the hip socket, but the frictional force f⃗f acts to prevent this clockwise rotation. The apparatus is designed such that when |F⃗h| > |f⃗f|, the femur head rotates clockwise. A sample of data collected at impending slippage of the femur is shown in the figure.(Figure 1). Based on these data, what is the approximate coefficient of static friction μs between the femur head and the hip socket?
Enter your answer numerically to one significant figure.
