9.29. Set Up: It takes the head for one back and forth cycle. So, it turns through in starting from rest. Solve: (a) gives (b) 9.30. Set Up: If the mass is distributed farther from the rotation axis, I is larger. Solve: (a) B (b) A (c) A 9.31. Set Up: The distances of the blocks from the axis are and Solve: 9.32. Set Up: (a) (b) (c) Solve: (a) (b) (c) 9.33. Set Up: (a) Each mass is a distance from the axis. (b) each mass is 0.200 m from the axis. (c) two masses are on the axis and two are from the axis. Solve: (a) (b) (c) Reflect: The value of I depends on the location of the axis. 9.34. Set Up: For a point mass, where R is its distance from the axis. Use Table 9.2 for the objects that have a distribution of mass. Solve: (a) (b) The mass at the axis makes no contribution to I . (c) 9.35. Set Up: (a) For a solid cylinder of mass m , and for a thin-walled hollow cylinder of mass M , (b) For a solid sphere of mass M , and for a thin-walled hollow sphere of mass M , I 5 2 3 MR 2 .

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
