EM 306 – Statics TEST 1 Fall 2008 - Landis Name ___________________________________ EID ___________________________________ Unique Number ___________________________ Instructions: Problem 2 requires a correctly drawn and labeled free body diagram. Show all of your work. Place a box around your final answers and include units. Problem 1. A plane is defined by points A , B and C . The distances OA , OB and OC are 2, 4 and 3 inches respectively. A force F is applied at point B . The magnitude of F is 200 pounds and it is directed perpendicular to the plane ABC with a positive z - component. (a) Determine the moment of the force F about point C . (b) Determine the component of F along the BC direction (i.e. how much of F is along the BC direction). (30 points) Problem 2. Draw a free body diagram and determine the reactions at points A and B . (20 points)

### 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.
