Q#1. Three cubes of side lo, 270, and 370, are placed next to another (in contact) with their centers along a straight line and the 1= 270 cube is in the middle (see Figure below). a) If the cubes are made of the same uniform material, find along this line the position of the center of mass of the system. b) We now replace the cube in the middle (1 = 270) by another cube of the same volume but made of a different uniform material. What would be the mass density p of this cube compared to the mass density po of the initial cube if we want to locate the center of mass of the new system at the interface between the cube in the middle (1 = 2/0) and the right-hand cube (1 = 310)? -210-310- Answers: a) xCM = 3.83lo; b) p = 4.75 p0.

Where is the center of mass of the two-stick system as depicted in the figure, with the origin located at the intersection of the sticks? b. Can the two-stick system be balanced on the end of your finger so that it remains lying flat in front of you in the orientation shown? Why or why not? FIGURE P10.18 (a) The center of mass of the stick on the x axis would be at (0.5 m, 0), and the center of mass of the stick on the stick on the y axis be at (0, 0.5 m), assuming the sticks are uniform. We can then use Equation 10.3 to find the x and y coordinates of the center of mass. xCM=1Mj=1nmjxj=12m[m(0.50m)]=0.25myCM=1Mj=1nmjyj=12m[m(0.50m)]=0.25m The location of the center of mass is (0.25m,0.25m) (b) No. The location of the center of mass is not located on the object, so your finger would not be in contact with the object. In a different orientation, balancing by applying a force at the center of mass might be possible, but not in the orientation shown.
