A 5.2-kg bowling ball rests on a uniform beam of length I and mass M, as in the figure. The beam is supported at two points separated by a distance BL where ß = 0.55 and the bowling ball is a distance d from support point 1. Find the largest distance dmax such that the beam does not tip if M = 15 kg and L = 4.6 m. [Note: To keep the bowling ball on the beam, report an answer of dmax ≤ L. For some values, a correct calculation gives dmax > L. That means the bowling ball can be placed anywhere on the beam without tipping and, in that case, the correct answer is dmax = L = 4.6 m.) dmax 2 k m L -BL- d M

Why is the following situation impossible? A uniform beam of mass m, = 3.00 kg and length e = 1.00 m supports blocks with masses m, = 5.00 kg and m, = 15.0 kg at tv positions as shown in the figure below. The beam rests on two triangular blocks, with point Pa distance d = 0.300 m to the right of the center of gravity of the beam. The position of the object of mass m, is adjusted along the length of the beam until the normal force on the beam at O is zero. d CG

A homeowner is trying to move a stubborn rock from his yard. By using a a metal rod as a lever arm and a fulcrum (or pivot point) the homeowner will have a better chance of moving the rock. The homeowner places the fulcrum a distance ?=0.288 mfrom the rock, which has a mass of 465 kg, and fits one end of the rod under the rock's center of weight. If the homeowner can apply a maximum force of 671 N at the other end of the rod, what is the minimum total length ? of the rod required to move the rock? Assume that the rod is massless and nearly horizontal so that the weight of the rock and homeowner's force are both essentially vertical. The acceleration due to gravity is ?=9.81 m/s2.
