A fluid‑like substance called synovial fluid lubricates the surfaces where bones meet in joints, making the coefficient of static friction between bones very small. For simplicity, assume the surfaces in the knee are flat and horizontal. Why is the minimum force required for initiating movement of bones in a typical knee joint different for different people, in spite of the fact that their joints have the same coefficient of static friction?

A plastic box is sitting on a steel beam. One end of the steel beam is slowly raised, increasing the angle of the surface until the box begins to slip. If the box begins to slip when the beam is at an angle of 41 degrees, what is the static coefficient of friction between the steel beam and the plastic box? 41°
on Two vertical walls are separated by a distance of 1.50 m, as the figure shows. Wall 1 is smooth, while wall 2 is not smooth. A uniform board is propped between them. The coefficient of static friction between the board and wall 2 is 0.851. What is the length of the longest board that can be propped between the walls? Wall 1 Wall 2 N
A wax is applied to the bottom surface of cross country skis to achieve a good balance between traction when the skier needs to climb a small hill and speed on downhill slopes. The coefficients of both static and kinetic friction between the waxed surface and snow increase as temperature decreases. If the temperature rises during the day and the skier begins to slip backward on hills they should re-wax their skis with what type of wax? One where the coefficient of static friction is larger. One where the coefficient of kinetic friction is larger. One where the coefficient of kinetic friction is smaller. One where the coefficient of static friction is smaller.
Running on a treadmill is slightly easier than running outside because there is no drag force to work against. Suppose a 60 kg runner completes a 5.0 km race in 15 minutes. Determine the drag force on the runner during the race. Suppose that the cross-section area of the runner is 0.72 m2. What is this force as a fraction of the runner's weight?
The coefficient of the static friction between the 100-lb box and the inclined surface is 0.10. The coefficient of the static friction between the rope and the fixed cylinder is 0.05.

A pulley is attached to one end of a rough plank, which makes an angle of 34° with the horizontal. A box is held at rest on the plank by a string that is attached to the box and passes over the pulley. A bucket of water is attached to the other end of the string and hangs freely. The coefficient of static friction between the plank and the box is 0.8. The box remains at rest but is on the point of slipping up the plank. The bucket of water has mass 7.5 kg. pulley box bucket of water 34° Model the box and the bucket of water as particles, the string as a model string and the pulley as a model pulley. (a) By considering the forces acting on the bucket of water, find the magnitude of the tension in the string (in newtons) in terms of g and the magnitude of the acceleration due to gravity (in ms-2).

You have a summer job working downtown washing windows on skyscrapers (the pay is great and so are the medical benefits). The platform you and your partner are using to get to the windows is a meter wide and four meters long. You know from hauling the platform out of your truck countless times that it has a mass of 70 kg. It is supported by two cables, one at each end, mounted on-center to prevent the platform from tipping over as it is pulled up the side of the building at a constant speed. If you (mass of 55 kg) are standing on the platform 1 meter from one cable while your partner (mass of 87 kg) is 1.3 meters from the other cable and both of you are half a meter from the side, what is the tension in each cable? Assume the platform has a uniform mass distribution and is of negligible thickness.
A block is resting on a wooden plank. There is a hinge on one end of the plank which allows the other end to be lifted to create an angle, θ, with respect to the horizontal as shown in the figure. The coefficient of static friction between the block and the plank is μs. If a student measures that the block begins to move at an angle of θ = 20.5°, what is the numerical value of the coefficient of static friction, μs?
