EM 306 – Statics TEST 2 Fall 2018 - Landis Name and EID ___________________________________ Unique # ___________________________________ All problems require correctly drawn and labeled free body diagrams for each component that you perform an equilibrium analysis on . Problem 1. Determine the reactions at A and the force in bar BC . Gravity acts downward and g = 9.8 m/s 2 . Only the mass m has weight. Note that there are two separate cables attached to the pulley at different radii . (20 points) Problem 2. Determine the shear force and bending moment distributions within the beam. The support on the left does not restrict vertical motion, but does restrict rotation. Direct plotting is acceptable (not required), but you need to indicate the type of function that you are drawing, e.g. linear, quadratic, cubic, etc., and all critical points must be clearly labeled. (20 points) Problem 3. Determine the shear force and bending moment distributions in the beam. Determine the magnitude and location of the maximum bending moment. Direct plotting is acceptable (not required). (20 points) a a q 0 q 0 a

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
