Problem 20DQ

When calculating the moment of inertia of an object, can we treat all its mass as if it were concentrated at the center of mass of the object? Justify your answer.

Step-by-Step Solution:
Step 1 of 3

Solution 20DQ Numerically, moment of inertia of an object is equal to the summation of the product of mass of each point mass and the square of its distance from the axis of rotation. In other words, moment of inertia depends on the distribution of mass of the object. Suppose, an object has point masses m ,m , …., 1 loca2ed at distnnces r , r ,..., 1 2 r nrom the axis of rotation respectively. Therefore, the moment...
