Question

Tasks:
At the instant shown, perform the following tasks using the individual values of lengths OA, AB, BC,
OE, CE, L, H, angle ?, angular velocity ???, mass ???, and moment of inertia ???. Length of the
walking beam BD is equal to 2·BC. Distance CG from point C to the centre of mass of the walking
beam is equal to ??/5

Velocity Analysis:
• Present a clearly labelled velocity diagram;
• Calculate the magnitude and direction of:
o velocity of point A;
o velocity of point B.
• Calculate angular velocities of links AB and BC.

I need further understanding how to draw and calcualte the velocity diagram
