- 4. Consider again the situation given in Problem 1. (a) Find the center-of-mass of the system made up of m, and m,, taking the origin to be at P. (b) Draw a free body force diagram with the all of the mass (m, + m,) concentrated at this center-of-mass position. (c) Find the torque about P due to (m, + m2) concentrated at this center of mass position. How does this result compare to (d) in Problem 1? [We will make use of this technique often for certain types of future problems.]1 a though dNumber 8
