TEST # 3, November 19, 2008 CE 180, Statics (02) STUDENT PLEDGE: I, _______________________, have not given or received improper aid on this quiz. INSTRUCTIONS: Read each problem carefully and think about the problems before you start to solve them. Show all your work neatly. A straight edge is not required. Clearly show your answers and use proper units. Draw Free Body Diagrams when needed 1. (2pts.) What is a free body diagram? 2. (2 pts.) Circle where the location of the largest Bending Moment is on the end beam below? 3. (2 pts.) In the beam in the photo above, what is the value of the shear force at the free end of the beam? 4. (2 pts.) Circle the name of the cross section property that governs torsion design: a. Radius of gyration b. Moment of inertia c. Polar moment of inertia 5. (2 pts.) Draw a simply supported beam and show the deflected shape if the beam
