Homework Statement
The link OA of a robots arm is rotating clockwise with a constant angular speed of 0.8 rad/s. At the same time the link AB is also rotating clockwise so that the end B moves down the vertical dashed line. Determine the angular speed and the acceleration of the link AB when...
okay, i think my answer is wrong but this is what I've got.
the moment is M(theta) is PRCos(theta) + F(R-RSin(theta)) where f is ficticious i know so do i disregard that.
Therefore M^2(theta) = R^2(P^2Cos^2(theta) + F^2 - F^2Sin^2(Theta).
Therefore i use that in the formula...
