Example 7.7 Buckle Up for
Safety
Goal Calculate the frictional force that
causes an object to have a centripetal acceleration.
Problem A car travels at a constant speed of 31.5
mi/h (14.1 m/s) on a level circular turn of radius 55.0 m, as shown
in the bird's-eye view in Figure 7.13a. What minimum coefficient of
static friction, µs, between the tires and the
roadway will allow the car to make the circular turn without
sliding?
Strategy In the car's free-body...

3. As part of a packaging process, cans roll along a ramp from one location to another. In one section, the cans 1) go through a curve and make a 90 degree turn and then 2) go down a ramp from one level to another. The cans have a diameter of 4 inches, a height of 4", and a weight of 1.61 lbs. The upper level is 4 feet above the lower level. The cans roll onto into the curve...

Question 1. What does the slope of the plot of tension
force vs. position represent?
Question 2. For the second run, do you notice nonlinear
behavior at high tension forces? Does this indicate the material is
becoming stiffer or slinkier?
Question 3. What does the trend in the graph indicate
will happen if you keep adding even more tension to the
wire?
Question 4. For a wire that has twice the radius of our
wire, how much would it stretch...
Pendulum Clocks Are Very Important...
1. Pendulum clocks are very important for the history of exploration. Accurate time was the best way to determine one's longitude, since the time of sunrise or sunset depends sensitively on your longitude. In this regard, the great enemy of accuracy was thermal expansion of the pendulum used for the chronometer. We are considering a large mass attached at the end of a brass rod. The mass at the end is much greater than the mass of the rod, so we...
