3 Problem 3 (6 points) A four-bar mechanism, shown in figure 2, has link lengths = 12 mm, L1 m 6 mm, L2 = 8 mm, L3 = 10 mm. Use the Grashof criterion todetermine wha type of four-bar mechanism this is, and circle the correct answer. Figure 2: Four-bar mechanism a) b) c) a triple-rocker mechanism a change-point mechanism a crank-rocker mechanism

Solution

b) change-point mechanism
