The crank OA rotates in the vertical plane with a constant angular velocity two = 7,9 rad/s. Link AB is a uniform slender rod. !! Determine the velocity of point A and the angular velocity of the link AB for the configuration when the crank OA is horizontal. 0.4 m 1.0 m 0.8 m Ltfen birini sein: O a.
