AAE 204 Fall 2011 Homework #4 Due start of class on Wednesday, 9 February 2011 The purpose of homework assignments is for students to gain further understanding of classroom principles through application to practical problems. Although discussion of assignments between students is permitted, the solution must represent your own efforts and understanding of the problem. Blatant copies of the solutions will not be accepted, and repeated evidence of copying will lead to failure of the course. The textbook referred to herein is: J. M. Gere and B. J. Goodno, Mechanics of Materials , 7 th Edition, 2009, Cengage Learning. 1. Do Problem 12.2-3 in the textbook . “Determine the y distance to the centroid C of a semicircle of radius r (see Case 10, Appendix D).”
