Question

Problem 1.15, Please write it on paper.

Problems 1.12 through 1.22 Refer to Figure 1.12a. For each of the following problems, (a) determine whether the links can actually form a mecha- nism with the dimensions given; (b) if a mechanism exists, identify the motion relationship (crank rocker, drag link, double rocker, triple rocker, or change point); (c) show the limiting positions if the mechanism is a crank-rocker, double-rocker, or triple-rocker mechanism: 1.15 L 1.5, L₁ = 4, L₂ = 2, L3 = 3.5. =

Link 3 (c) FIGURE 1.12 (a) Crank-rocker mechanism. For this class of mechanism, continuous rotation of the driver results in oscillation of the follower. (b) A limiting position of the crank-rocker mechanism (flexed). (c) A limiting position of the crank-rocker mechanism (extended). fixed link) are collinear. From geometry, the length of one side of a triangle must be less than the sum of the lengths of the other two sides. Applying this notion to parts b and c of the figure, we obtain Link 3 (1.8)
