Question
Chapter 12, Problem d01
Because g varies so little over the extent of most structures, any structure's center of gravity effectively coincides with its center of mass. Here is a
fictitious example where g varies more significantly. The figure shows an array of six particles, each with mass m, fixed to the edge of a rigid structure of
negligible mass. The distance between adjacent particles along the edge is 1.90 m. Following are the values of g at each particle's location:
Particle 1: g =8.03 m/s2
Particle 2: g = 7.71 m/s2
Particle 3: g= 7,68 m/s2
Particle 4: q 7,47 m/s2
Particle 5: q= 7.68 m/s2
Particle 6: g = 7.71 m/s2
Using the coordinate system shown, find (a) the x coordinate xcom and (b) the y coordinate ycom of the center of mass of the six-particle system. Then
find (c) the x coordinate x and (d) the y coordinate y of the center of gravity of the six-particle system
