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 AB = 4.8 rad/s. At the instant shown, when angle = 75, determine: a. The magnitude of the velocity of point B. | UB|= m/s. Give your answer to 4 significant figures. b. The velocity of the point B resolved parallel and perpendicular to CD, (1 mark) (UB) along CD towards C =. (UB) perpendicular to CD = m/s. 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, JUD. FB|C == @CD m. |VD] = rad/s. m/s.
