Problem 2 In the design of the collar-crank wheel with r = 1.2m, motion is supplied by the wheel, which at the instant shown has woA = 2.8 rad/s (clockwise CW) and OA = 0.5 rad/s (counterclockwise CCW). Determine the velocity vB and acceleration a of collar B as well as the angular velocity @AB and acceleration of link AB using the vector approach. State type of motion for every RB involved. Draw IC for link AB (without solving). Note 1: If you don't use vector notation properly (in both 2b and 2c) - you will loose 1 point! 45 2r B 30 Note 2: TAs will focus on grading the method of attack in this assignment with the particular focus on 2a, 2b. The proper 2a diagram can be found in the Diagram Sheet. 2c will be markled by completions with some reduction for the wrong answers/methods (without detailed feedback).
