The figure shows a crank AB rotating about point A , attached via a slider at B to a rod CD which rotates about point c. The distance AC is 1.1 m, the crank AB is of length 1.1 m and the crank CD is of length 1.3 m. The crank is rotating with constant velocity MAB = 4.8 rad/s. At the instant shown, when angle 0 = 75, determine: a. The magnitude of the velocity of point B. TUB| = m/s. Give your answer to 4 significant figures. (1 mark) b. The velocity of the point Bresolved parallel and perpendicular to CD, (UB)along CD towards c =. m/s. (UB)perpendicular to CD =. m/s. Give your answers to 4 significant figures. (1 mark) c. Calculate the distance from C to B, Bic, and hence, or otherwise, determine the angular velocity of CD, CD, and the magnitude of the velocity of D, lupl. IBC = m. WCD = rad/s. lupl = m/s.
