Question

3. (20 points) A linkage is to be designed to carry the object in Figure 1 from position R to position P at the orientations shown. The chosen values are given as z 2.40, ø - 100° for Z at position 1 and B3 1209. Use analytical synthesis without regard for the fixed pivots shown to obtain W for the left dyad of the resulted four-bar linkage. (30 points) A linkage is to be designed to carry the object in Figure 1 through the three positions R P, and P at the orientations shown. Use analytical synthesis without regard for the fixed pivots shown to obtain Wand Z for the left dyad of the resulted fourbar linkage (Provide the necessary values and the relevant expressions/equations for obtaining the solution). The chosen values are given as B260 and B3 1200. 1. 1.903 1.389-P 39° P, 1.347 1.830 63 1.25 0.884 101 3.062 Figure 1
