Chapter 5, Problem 4CQ
When you push a piece of chalk across a chalkboard, it sometimes screeches because it rapidly alternates between slipping and sticking to the board. Describe this process in more detail, in particular explaining how it is related to the fact that kinetic friction is less than static friction. (The same slip-grab process occurs when tires screech on pavement.)

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. Determine the force the woman must exert on the rope to cause the box to start moving up the inclined surface. What is the minimum force the woman must exert on the rope to hold the box in equilibrium on the inclined surface?
Question 19
In order to prevent muscle contraction from misaligning bones during healing (which can cause a
permanent limp), injured or broken legs must be supported horizontally and at the same time kept
under tension (traction) directed along the leg. One version of a device to accomplish this aim, the
Russell traction apparatus, is shown in the figure below. This system allows the apparatus to support
the full weight of the injured leg and at the same time provide the traction along the leg. If the leg to be
supported weighs 47.0 N, what must be the weight of W?

- The two blocks (m= 16 kg and M = 88 kg) are not attached to each other.The coefficient of static friction between the blocks is ms =0.38, but the surface beneath the larger block is frictionless.

(Some of the options mention a horizontal force that friction opposes. This means that a force is pulling horizontally and friction is acting in the opposite direction.) Your answer: The force of kinetic friction changes if the speed of the object decreases. The force of kinetic friction changes if the horizontal force (or forces) it opposes gets weaker. The force of static friction changes if the speed of the object decreases. The force of static friction changes if O the horizontal force (or forces) it opposes gets weaker.arrow_forward
