Hi. I have problem with this question. If you would mind helping me please post the solution in a clear way and visible photo :) Thanks in advance!

Determine the angular velocity w of the rod AB of the crank mechanism in the position shown. The crank OA of radius r rotates with an angular velocity wo, and the length of the rod AB is L.

Solution

The angular velocity of the rad AB is zero

Since at this position the connecting rod does not have angular velocity
