1 ME 352 - Machine Design I Name of Student___________________________ Spring Semester 2011 Lab Section Number_______________________ EXAM 1. OPEN BOOK AND CLOSED NOTES. Wednesday, February 16th, 2011 Use the blank paper for your solutions and write on one side of the paper only. Do not write your solutions on the exam pages. However, you can use the given figures to clearly show your vectors and instantaneous centers of velocity. Staple your crib sheet to the end of Problem 1. Problem 1 (25 Points) . Part A. (i) Determine the mobility of the mechanism shown in Figure 1(a). Clearly number each link and label the lower pairs and the higher pairs on the figure. (ii) Define vectors that are suitable for a kinematic analysis of the mechanism. Label and show the direction of each vector on Figure 1(a). (iii) Write the vector loop equation(s) for this mechanism and identify: (a) suitable input(s); (b) the known quantities; (c) the unknown variables; and (d) any constraints. If you identified constraint(s) then write the constraint equation(s).
