Question

Exercise 9.29 Part A Calculate the moment of inertia of each of the following uniform obiects about the axes indicated. Consult Table Moments of Inertia of Various Bodies in the Textbook as needed A thin 3.80-kg rod of length 85.0 cm, about an axis perpendicular to it and passing through one end kg m Submit My Answers Give Up Part B A thin 3.80-kg rod of length 85.0 cm , about an axis perpendicular to it and passing through its center. g m Submit My Answers Give Up Part C A thin 3.80-kg rod of length 85.0 cm , about an axis parallel to the rod and passing through it. 2 Submit My Answers Give Up

Explanation / Answer

1) I = 1/3* ML2 = .915 kg-m2

2) I = 1/12* ML2 = .228 kg-m2

3) The radius of the rod is required for this part.

4) I = 2/5* MR2 = .1458 kg-m2

5) I = 2/3* MR2 = .243 kg-m2

6) I = MR2 = 6*(.30/2)2 = .135 kg-m2
