I ve tried to solve this problem in so many ways but still didn't manage to do it...
What would be the correct way to solve it please?
This arm of this mechanism has a length of 0,2m. The piston has an angular velocity of 2000 tours/min. What would be the velocity of point D for an angle theta of 60 degrees?
I think that what I am missing is the angle formed by the arm and the line, which is 50mm long. Example like here (different exercise):
I am trying to look for this angle beta which could help me solve the problem
