EM 306 – Statics TEST 1 Spring 2007 - Landis Name ___________________________________ EID ___________________________________ Unique Number ___________________________ Instructions: Both problems require 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. The unstretched length of the spring CD is 350-mm. The lever ABC exerts a contact force of 120-N on the frictionless surface at A . (a) Determine the value of the spring constant k , and (b) the reactions at B. Recall that a linear spring exerts a force F s = k L ! L 0 ( ) , where k is the spring constant, L is the stretched (current) length of the spring, and L 0 is the unstretched length of the spring.
