Bar BC of the linkage slides in the collar D. If bar AB is rotating clockwise with constant angular velocity of 12 rad/s, determine the angular velocity of BC when it is in the horizontal position shown.

1. A slotted link (horizontal at the instant shown) pivots about point C and is driven by a pin at point P located on the bar AB, which makes an angle of 0 = 35°, as shown. The distance from A to P is 24". At this instant in time, the distance from C to P is 18". If the angular velocity of bar AB is 2 rad/s clockwise, calculate a. The angular velocity vector of the slotted link. b. The velocity vector of the pin with respect to the slotted link. В C A

At the instant shown, an overhead garage door is being shut with point B moving to the left within the horizontal part of the door guide at a speed of 6.5 ft/s, while point A is moving vertically downward. Determine the angular velocity of the door and the velocity of the counterweight C at this instant if L = 6 ft and d = 1.5 ft. 88 floor B The angular velocity of the door is The velocity of the counterweight Cis k rad/s. j ft/s.

At the instant shown, rod CD has a constant clockwise angular velocity WCD- The collar at C is pin connected to CD and slides freely along AB. If the velocity of point Care 7c = 1.3 m/s, the relative velocity of C to A in the rotating coordinates (C/A)zy = (VC/A)zy (0.8667 -0.500) m/s, and the position vector C/A=0.73(0.8667-0.5007) m, -(0.73) (0.500) knowing that (vC/A)zy WAB 0.866 determine the angular velocity of link AB, WAB.

The slider block C moves at 10 m/s down the inclined groove. Both links have the length b -1.8 m. Determine the angular velocity of link BC, at the instant shown. (See figure 04)

The figure below shows a cargo lift mechanism for a delivery truck At this instant, point A has a velocity of 12 in/s in the direction shown, and point B has a velocity of 10.4 in/s also in the direction shown. Determine the angular velocity of the lower link and the relative velocity point B relative to point A.

Q1. Use the graphical method only, find the velocity of the piston for the system shown below and the angular velocity of the link AB about point A. The crank OA rotates counter clockwise at 3000 rev/min. If the angular acceleration of the crankshaft OA is 1200 rad/s, determine the angular acceleration of the connecting rod AB. Assume that OA = 150mm, AB = 250mm, angle BOA = 60°, ABO = 25°. G
