Center of Gravity of a system

The centre of gravity is a property that is based on the geometry of a rigid body or any particle. It is described as an equilibrium point or a hypothetical location where the total weight of the body is concentrated.

Two metersticks are connected at their ends as shown in Figure P10.18. The center of mass of each individual meterstick is at its midpoint, and the mass of each meterstick is m. a. 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.

In exercise physiology studies, it is sometimes important to determine the location of a person’s center of mass. This determination can be done with the arrangement as shown.

The center of mass of a person may be determined by an arrangement such as the one shown in the figure below. A light plank rests on two scales separated by a distance of d = 1.80 m and reading Fg1 = 470 N and Fg2 = 260 N. Determine the distance of the girl's center of mass from her feet.
Two ice skaters, starting from rest, hold onto the ends of a 10m pole. A 40-kig player is at one end of the pole and a 60-kg player is at the other end. The players then start pulling themselves themselves along the pole towards each other while sliding without friction on the ice. If the two skaters continue past each other after they meet, what distance will the 60-kg player have moved with respect to the ice when the skaters have exchanged positions with respect to each other? Please clearly explain each step. I know it has something to do with the center of mass not moving. But why does the center of mass not move? Please explain.
A large airplane typically has three sets of wheels: one at the front and two farther back, one on each side under the wings. Consider the Boeing 787 "Dreamliner", with a mass of 198000 kg. In this particular model, the distance from the front wheels to the rear set of wheels is 23.8 m. a) If the center of mass of the airplane is along a line through the center and 3.00 m in front of the rear wheels, how much force, in meganewtons, does the ground exert on each set of rear wheels when the plane is at rest on the runway? b) How much force, in meganewtons, does the ground exert on the front set of wheels?

A 63kg beam extends horizontially from the side of a wall. A 13kg box hangs from the end of the beam. The beam is also supported by a cable that is connected to the side of the wall, the cable is also attached to the beam 3/4 of the way from the wall to the end of the beam, it makes a 32 degree angle with the beam.
