7 A four-bar linkage with an open configuration is shown in Figure 1. The relevant data for the linkage is provided in Table 1. 3 A 120° Figure 1: Four-bar linkage 02 a 2 Link 1 Link 2 Link 3 Link 4 100 mm 40 mm 100 mm 120 mm 02 120° 03 47.3° 04 115.7° 45 rad/s Orad/s2 Table 1: Data for four-bar linkage a. Analyse, via vector loop method, the mechanism by determining i. The angular velocity ws and W4, and ii. The angular accelerations as and a4 iii. The acceleration (magnitude and direction) of point A, AA and B, A3. Hint: The accelerations AA, ABA and As are given by + A 4 = a02 (-sinê, + jcos 2)- ao (cosť, + jsin (2) A BA = ba:(-sin 8+ jcos 03) – bo (cos 6, + jsin 3) Ag =cQ4 (- sin 04 + jcos 64 )-cm (cos84 +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.
