There are two moving parts Part 2 and Part 3 connected at po

There are two moving parts (Part 2 and Part 3) connected at points O and A. Part 1 is a fixed part connected to absolute ground. Part 2 is rotating at a constant angular velocity of w_2, and Part 3 is rotating at a constant angular velocity of w_3. Please state what the joints are in the system. Using your knowledge of computational kinematics determine the following: If you cannot do the mathematics, then please explain what you believe is the procedure to calculate each variable. Also, explain what each of the above variables mean.

Solution

The joints present in the mechanism are rotating joints which has 1 dof ...

Velocity of part2 is absolute and will be obtained directly,, whereas velocity of link3 is relative and is depends on velocity of link 2
