Chapter 10.2, Problem 10.74P
In Prob. 10.40, determine whether each of the positions of equilibrium is stable, unstable, or neutral. (See the hint for Prob. 10.73.)
10.40 Solve Prob. 10.39, assuming that P = 350 N, l = 250 mm, and K = 12.5 N·m/rad. Obtain answers in each of the following quadrants: 0 < θ < 90°, 270° < θ < 360°, and 360° < θ < 450°.
10.39 The lever AB is attached to the horizontal shaft BC that passes through a bearing and is welded to a fixed support at C. The torsional spring constant of the shaft BC is K; that is, a couple of magnitude K is required to rotate end B through 1 rad. Knowing that the shaft is untwisted when AB is horizontal, determine the value of θ corresponding to the position of equilibrium when P = 100 N, l = 250 mm, and K = 12.5 N·m/rad.
