000 CE 2313 Mechanics of Materials Examination II March 29, 2007 Name: _______________________________________ There are 5 numbered, equally weighted problems on this exam. Time allowed for the exam is 80 minutes. Read the problems carefully and don’t waste time doing work that is not requested. Problem statements may include information that you do not really need. Provided values have at least three significant digits even when not expressed that way. Draw Free Body Diagrams (or other diagrams) when appropriate!!!! Show each problem solution in detail. Test credit will be based primarily on your solution method rather than your numerical solution. If you are filling each page, you are probably doing too much. If you do need additional space for a solution or scratch paper, use the back of the preceding test page.
