* HOMEWORK NOTES AND HINTS *
2.41: HINT: Align x-axis with member BC, thus Ry=0.
2.45: NOTE: Solve analytically, then use the Working Model simulation on the software supplied with your text book to obtain values and plot FBC vs. a . Comment on whether it is easier for the person to pull the weight if the person is closer to the weight or farther from it, and why.
2.65: HINT: Do it in terms of components and consider pulleys to be particles, i.e., have radii = 0.
2.93: NOTE: Point A is in the x-y plane.
3.58: HINT: For coordinates of point E: BC = 60 inches, and BE/BC = ¾.
3.102: NOTE: For equivalence, consider only 3.101 (f), (g), and (h).
3.120 HINT: Replace the belt forces on each pulley with equivalent force-couple systems acting at the center of each pulley. Thus you do not need to determine the points of contact of the belts with the pulleys.
