- Homework Statement:
- If the angular velocity of link AB is w(AB)=4 rad/s at the instant shown, determine the velocity of the sliding block E at that instant. Also, identify the type of motion of each of the four links.

- Relevant Equations:
- V = w(r)

Hi! everyone! ;)

I have a problem with the development of this problem.

I need to resolve it with 2 procedures: trigonometry and instant centers. My advance can be see in the next image:

The instant centers procediment its (1) up and trigonometry procediment its (2) down.

I know that the result its 4 rads/s. But in my answer its not make the sense ;( and i don't know why the angular velocity of "D" its 4 rads/s.

PD: I don't can use cross product for resolve it... only trigonometry and instant centers (separately).

Thanks for read ;)
