Link Length (mm) OA 80 AC 120 CB 120 CD 120 A O130° B Crank OA rotates at 150 rpm CCW. Determine the velocity and acceleration of B and D, and the angular acceleration of links AB and CD.

Determine the angular acceleration of link CD if link AB has the angular velocity and angular acceleration shown (Figure 4).

5. For the following pin-collected link assembly, link AO is pinned at point O, and moves with angular velocity W and angular acceleration a (both counterclockwise). 3) if W = 2.2 rad/s and a = 7.9 rad/s2, what is the magnitude of the linear acceleration of point A in m/s²? Hint, don't forget linear acceleration has two components, normal and tangential. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. B Your Answer: 8 Answer 0.5 m ω, α

5. For the following pin-collected link assembly, link AO is pinned at point O, and moves with angular velocity w and angular acceleration a (both counterclockwise). 6) if W = 5.3 rad/s and Q = 7.0 rad/s?, length I = 1.8 m, and angle 0= 36°, what is the angular acceleration of link AB in rad/s?? Please pay attention: the numbers may change since they are randomized. Negative must be included if it is clockwise. Your answer must include 2 places after the decimal point. 0.5 m O, a

1. At the time the crank AC is at 30° the collar is 6" from point A and crank BC is horizontal. The crank AC is rotating at 3 rad/s counter clockwise. The collar C is free to slide on the frictionless crank AC. What is the total acceleration of point C? 3" В A

In the mechanism shown below, link AB rotates at a constant angular velocity of 1.5 rad per sec counterclockwise. What is the acceleration of C along the channel? Assume the positive direction to be upwards and to the right. use relative motion

60⁰, According to linkage shown in the figure, Link 3 must be perpendicular to link 2. If the angular velocity of link 2 is 100 rad/sec CW and Using loop closure method, calculate the acceleration of point C and the angular acceleration of link 3. B 10" 3 = 3
