Question:

The two rotor blades of 800-mm radius rotate counterclockwise with a constant angular velocity w = θ˙ = 2 rad/s about the shaft at O mounted in the sliding block. The acceleration of the block is aO = 3 m/s2. Determine the magnitude of the acceleration of the tip A of the blade when 

(a) θ = 0, 

(b) θ = 90°, 

(c) θ = 180°. 

Does the velocity of O or the sense of w enter into the calculation?
