A four-bar linkage with an open configuration is shown in Figure 1. The relevant data for the linkage is provided in Table 1. A 2 120° Figure 1: Four-bar linkage W2 a2 Link 1 100 mm Link 2 40 mm Link 3 100 mm Link 4 120 mm 02 120° өз 47.3° 04 115.7° 45 rad/s 0 rad/s2 Table 1: Data for four-bar linkage a. Analyse, via vector loop method, the mechanism by determining i. The angular velocity w3 and W4, and ii. The angular accelerations a3 and a4 iii. The acceleration (magnitude and direction) of point A, AA and B, AB. Hint: The accelerations AA, ABA and AB are given by A A = a0.2 (-sin 02 + jcosez)-awź (cos 02 +jsin 62) A BA = baz(-sin 03 + jcos 83) - boš (cos 03 +jsin 63) Ap=cQ_(-sin 04 + jcos04)-což (cos 64 +jsin 04) b. Demonstrate graphically by sketching any one of the possible toggle positions of the above mechanism. Label the links in your sketch clearly.
