In a four-link mechanism, the dimensions of the links are given as AB=50mm, BC=66mm, CD=56mm, and AD=100mm. At the instant when <DAB = 60° , the link AB has an angular velocity of 10.5 rad/sec in the counterclockwise direction. Both A and D lies in the horizontal plane.For the given configuration of the mechanism, determine the following: angular velocity of the link CD, angular velocity of the link BC, velocity of an offset point G on the link CD if CG=24mm,DG=44mm Instructions: configuration diagram Scale: 1:1 velocity diagram.

(Three-Dimensional Motion) The figure below represents a pair of bevel gears A and B. Gear A rotates in ahorizontal plane about a vertical axis at O. Gear B rotates around the shaft OC,which in turn rotates about the terminal axis at O. At the instant shown, theangular velocity of the shaft OC is 10j rad/sec, and gear A is stationary. Deter-mine the angular velocity of gear B, and the velocity of a point D at the top ofgear B.

- The wheel of radius 0.7 ft rolls without slipping on the horizontal surface with a constant angular velocity w. At the instant when 40°, point A on the wheel has a speed of 2.3 ft/sec. Calculate the angular velocity of the wheel and the speeds of the center O and point B on the wheel. (w = 3.89 rad/sec, vo = 2.72 ft/sec, vB = 4.93 ft/sec) A ω B 0 0

(b) The disk cam is controlled by the 5" slotted arm AB through a pin P fixed on the disk. If at the instant shown, 0 = 60°, 0 = -0.1 rad/s, and 6 = -0.2 rad/s², find the angular velocity w and the angular acceleration a of the disk at the instant.

Arm AB has a clockwise angular velocity ωAB while the ring gear R has a counterclockwise angular velocity ωR. Using the Instantaneous Center (IC) Method, determine (a) the angular velocity (in rad/s) of gear B and (b) the velocity (in cm/s) of gear tooth D at the instant shown. Also, (c) illustrate the location of each rigid body’s instantaneous center. Utilize the following given:s = 13.5 cmrB = 6 cmωAB = 0.55 rad/sωR = 0.16 rad/s
