Question

Explain and derive relation for center of madd of uniform rod and disk

Answer 1

Answer:

The easiest rigid body for which to calculate the center of mass is the thin rod because it extends in only one dimension. ... The center of mass of a uniform rod is at the center of the rod. So, for instance, the center of mass of a uniform rod that extends along the x axis from x=0 to x=L is at (L/2, 0).
