Chapter 5, Problem 68P
Take μk = 0.75 in Example 5.11, and plot the tension force in units of the trunk’s weight, as a function of the rope angle θ (that is, plot T/mg versus θ). Use your plot to determine (a) the minimum tension necessary to move the trunk and (b) the angle at which this minimum tension should be applied.
