Unformatted text preview: ME 104: Engineering Mechanics II Spring Semester 2011 Department of Mechanical Engineering University of California at Berkeley Professor Oliver M. O’Reilly Homework No. 11 Due by 2:30 pm on Friday April 15 2011 Notes: (i) The first 5 problems in this week’s homework all involve calculating inertias of various bodies. You will need to look at Table D/4 in Meriam and Kraige and also look at their Appendix B. (ii) The last two problems pertain to purely translational motion of rigid bodies. For them, ω = . Conse quently, the angular momentum of the rigid body relative to its center of mass H = , and the balance laws simplify to F = m ¯ a , M = . (1) These equations represent 6 scalar equations. When calculating M be careful when using r × F to calculate the individual moments  it is easy to make an algebraic mistake. (iii) The points total for this homework is 80: Problems 3, 5, and 6 will be graded and 2 of the remaining 4 problems will be graded....
