A four-bar linkage is shown in the figure (the ground "link" OC is considered the fourth bar). If the drive link OA has a counterclockwise angular velocity o-5.0 rad/s, determine the angular velocities of links AB and BC. The angular velocities are positive if counterclockwise, negative if clockwise 16° 455 mm 355 135 mm 53° 0 Answers: AB 0.213 B0.380
3. Link 2 (AB) of the slider crank inversion shown in Figure 3 is rotating at a constant 2 11.00k(rad/s). Determine the angular velocity of link 4 (DC) at the instant shown in the figure. Hints: The angle between links 3 and 4 is fized so they have the same angular velocity. Consider Cs as point on Link 3 sliding through the bearing on link 4. (100 points) C3 90° A = (0,0).

For the planar mechanism of figure below, link 4 servers as slider support which is free to rotate about the z axis, but has point D kept stationary. Link 3 is a rigid member continuous over the rotational joint B. The lengths of the links 2 and 5 are respectively 3 cm and 7 cm, and the distance AB is 6 cm. The angles of the links 2, 3, and 5 with the positive horizontal are denoted as θ2 ,...
