Find the veocities Va, Vg, and Vpox for the mechanism shown below. Link 2 (Line joining O24) is oriented at 60 in the global coordinate system at the instant shown in the figure, and is rotating clockwise with an angular velocity 2 of 30 rad/sec. (Hint: This is a parallelogram linkage, which exactly duplicates the rotary motion of the driver crank at the driven crank). L = 150 L2= 30 L3 = 150 L4= 30 %3D box %3D YA 02 4
