Solutions To FE Exam 2 - California State University, Los Angeles

Solutions to FE Exam “Dynamics” Review Problems; Problems are Online at McGraw-Hill Website Prepared by Stephen F. Felszeghy CSULA Emeritus Professor of Mechanical Engineering Start the web page for the book: Beer and Johnston, Vector Mechanics for Engineers, Statics and Dynamics, Ninth Edition, 2010, at: nformation center view0/ . Look for the “Online Learning Center” box on the left. Click on the “Student Edition” link. Select a chapter from the pull-down menu. My solutions, which you will find below, are for the online problems that are associated with the following chapters and topics: Chpt. 11: Chpt. 12: Chpt. 13: Chpt. 14: Chpt. 15: Chpt. 16: Chpt. 17: Chpt. 19: Kinematics of Particles Kinetics of Particles: Newton's Second Law Kinetics of Particles: Energy and Momentum Methods Systems of Particles Kinematics of Rigid Bodies Plane Motion of Rigid Bodies: Forces and Accelerations Plane Motion of Rigid Bodies: Energy and Momentum Methods Mechanical Vibrations Click on “FE Exam Review.” Solve the problem, and select the answer from the multiple choices at the bottom. Click on the right-arrow to continue to the next problem. This process ends when you click on the right-arrow for the third time. To try to solve other problems from the same chapter, you will need to exit by clicking on, say, Chapter XX at the top, and restart “FE Exam Review.” Now you will be presented with all new, or a mixture of old and new, problems. After repeated trials, no new problems will appear. As I mentioned in class, some of the online problem statements have errors in them, and some solutions and answers are wrong. For this reason, I have prepared a separate document that lists the errors and corrections. You can access this document at: s/u28426/felszeghy/fe exam review rev3.pdf . Although I shared the errors and corrections with McGraw-Hill, the company has not made any corrections on its Website. The online problems are not numbered, except for being associated with chapter numbers. For this reason, I downloaded the online problems in no particular order, and numbered them consecutively in a decimal format, XX.X, where XX refers to the chapter number, and X stands for the sequence number. All the online problems numbered this way are included in the above “FE Exam Review rev3.pdf” document under the heading: “Part 1, FE Exam Review, Online Problems and Solutions.” My own solutions, which you will find below, follow the problem numbering scheme I established above. I include sketches in my solutions to allow you to identify the problems to which my solutions apply without necessarily having to refer to Part 1 of the above “FE Exam Review rev3.pdf” document. I wish you all the best on your computer-based FE exam!
