Question

In the mechanism of figure Q1 crank O-A rotates at 120 rev/min clockwise about rotational speed. Slider B slides on sliding link AC. The are as follows: O2A 6,0 cm, CD 10 cm, AB 2 cm, AC 8 cm, OsD 4 cm and Angle θ2-1 100 and θ5 100. Construct a velocity diagram for this position and the O2 at a constant dimensions of the links of the mechanism [10] n find the rotational speed of link OsD. 0, (-7.0, 10.0) o, (-2.0, 2.0) Os (0, 0) 05 Figure Q1

Please change the rotational speeds of link 02-A from 120 r/min to 75 r/min and add a rotational speed of N = 100 r/min to link 05-D. RESPECTIVILY.
Then find the rotational speed of link 07-B. FROM THE VELOCITY DIAGRAM.
Thank you.
