3. in the figure below, bar A has an angular velocity of 0.25 rad/sec clockwise and an angular acceleration of 0.15 rad/sec counterciockwise. At the instant shown, find the angular acceleration of bar B.

At the instant shown, the shaft and plate rotate with an angular velocity of 14 rad/s and angular acceleration of 7 rad/s?. Determine the speed and acceleration of point D, located in the corner of the board right now. Express the result in the form of a Cartesian vector. 0.6 m 0.2 m 0.4 m 0.3 m 0.3 m 0.4 m

A four-bar linkage is shown in the figure (the ground "link" OC is considered the fourth bar). If the angular velocity and angular acceleration of drive link OA are 6.1 rad/s and 6.6 rad/s² respectively, both counterclockwise, determine the angular accelerations of bars AB and BC for the instant represented. The angular accelerations are positive if counterclockwise, negative if clockwise. The answers are not 2.356 and 11.327, or 390.82 and 465.7

Crank OA rotates with a constant counterclockwise angular velocity of 8.2 rad/s. Determine the angular acceleration AB of link AB for the position shown. The angular acceleration is positive if counterclockwise, negative if clockwise. Assume a = 80 mm, b = 70 mm, AB = 145 mm. a Answers: CAB= i rad/s² B
