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 Additional Help and Intermediate Results Notes: In case you get bogged down with some of the intermediate details in the homework problems, here are supplemental details which will hopefully be of help. 1. Problem B/7 (10 Points) Use Table D/4 of Meriam and Kraige and the parallel axis theorem to find I xx . You are asked to compare the value of the moment of inertia computed using the parallel axis theorem to that obtained by assuming I xx = md 2 . 2. Problem B/13 (10 Points) To solve this problem, calculate I xx for the ”hole” of radius r 1 and subtract it from I xx for the solid cylinder of radius r 2 (i.e., the cylinder without the hole). To avoid problems with masses, use the fact that the mass = volume times the density....
