Three large dogs (Labrador Retrievers: Barky, Chompers and Dancer) are on a bridge betweentwo posts, A and E. The weights of three Labradors are: WB = 85 lb, Wc = 70 lb, and Wp = 65 lb.The Labradors run off the bridge to swim in the river below. A very large dog (Saint Bernard)lopes onto the bridge. In order for the system of the three Labradors to be equivalent to the SaintBernard, determine: (a) the required weight of the Saint Bernard (that is, what is the resultantforce of the three Labradors), and (b) where must the Saint Bernard stand (that is, determine the%3D%3D%3Ddistance, d, from point A.)

3. A uniform, 200-kg plate is kept in static equilibrium by two hinges, A and B, and a single cable, DCE. a) Draw the FBD of the plate. b) Write the coordinates of each named point in the figure (A, B, etc.) and any additional point where a force or moment is acting. c) Is this system statically determinate? Explain your answer. d) Is this system completely (i.e., properly) constrained? Explain your answer. e) Assume the hinges are properly aligned and do not exert any reaction moments on the plate. Determine the tension force on the cable DCE for this plate to stay in static equilibrium. (Hint: when a rigid body is in static equilibrium, the resultant moment about any point or line has to be equal to zero.

The figure on the left, below, shows a non-uniform bent rod with a mass of 5 kg. Your job is to determine the location of the center of gravity of this rod. You design an experiment: you connect a pin and cable to the rod such that it safely stays in static equilibrium under a force P that you apply. Then, you apply forces between 0-100 N, and measure the tension force on the cable using a cable tension meter. The results of your experiment are shown in the figure, on the right. Using this experiment, calculate (approximately) the horizontal distance (x in the figure) between point A and the center of gravity G of the bent rod.

1) The first man who studied and partially understood the kinematics of a particle falling in the earth's gravitational field was Leonardo da Vinci (1452-1519). He constructed an apparatus consisting of two vertical boards, hinged together on one side and covered with blotting paper on the inside faces. A leaking water tap lets drops fall down between the boards at presumably equal intervals of time. When a string is suddenly pulled, the boards are clapped together and the positions of the drops on the blotters can be inspected. Suppose that the vertical boards are 3 feet long and the leaking faucet is at such height and the rate of dropping is so regulated that when a drop is just coming out of the faucet, the next or second drop is just at the top of the boards and the sixth drop is at the bottom of the boards, while drops 3, 4 and 5 are between the boards. Calculate the number of drops leaving the faucet per second. ANS. 11.35 drops/sec
The expression: "If the vector sum of the external forces on a system is zero, the total linear motion of the system ..." Complete the sentence with the best option that completes the expression: a) It is constant and the utility lies in that it does not depend on the detailed nature of the internal forces acting between the members of the system. b) It is constant and the utility lies in that it depends on the detailed nature of the internal forces acting between the members of the system. c) It is not constant and the utility lies in that it depends on the detailed nature of the external forces acting between the members of the system. d) It is not constant and the usefulness is that it does not depend on the detailed nature of the external forces acting between the members of the system.
