A physical pendulum consists of an 85-cm-long, 240-g-mass, uniform wooden rod hung from a nail near one end (Fig. 14-38). The motion is damped because of friction in the pivot; the damping force is approximately t proportional to d6/dt. The rod is set in oscillation by displacing it 15 from its equil

Diesel Cost and Market Areas Consider Figure 23 , which shows the market areas of sugar-beet processing plants. Suppose that an increase in the price of diesel fuel doubles the cost of hauling sugar beets from farms to processing plants. Modify Figure 23 to show the effects of higher transport costs.
