Analyse, via vector loop method, the mechanism by determining i. The angular velocity w3 and W4, and ii. The angular accelerations a3 and 24 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 = aQ2 (-sin 02 + jcos@z)-ao (cosez + jsin 02) A BA = baz(-sin 03 + jcos83) - boz (cosez + jsin03) Ap=cQ4 (-sin 04 + jcos64)-co (cos 6 4 +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.
