Question

Problem 9.31 A uniform bar has two small balls glued to its ends. The bar is 2.20 m long and with mass 2.40 kg , while the balls each have mass 0.600 kg and can be treated as point masses. Part A: Find the moment of inertia of this combination about an axis perpendicular to the bar through its center. Part B: Find the moment of inertia of this combination about an axis perpendicular to the bar through one of the balls. Part C: Find the moment of inertia of this combination about an axis parallel to the bar through both balls. PLEASE HELP

Explanation / Answer

a) M L^2/ 12 + 2 m (L/2)^2 Here M- mass of the bar, m-mass of ball, L-length of the bar. b) M L^2 /3 + m L^2 c) Zero d) (M+2m) (1/2)^2 Hope you can plug the values and get the required.
