Consider the double-slider linkage in the posture given in Prob. 3.8. Point B moves with a constant velocity VB = 40 m/s to the left, as shown in the figure. The angular velocity and angular acceleration of coupler link AB are ω3 = 36.6 rad/s ccw and α3 = 1340 rad/s 2 cw, respectively. For the absolute motion of coupler link AB in the specified posture, draw the inflection circle and the Bresse circle. Then determine:

(a) the radius of curvature of the path of point C, which is a point of link 3 midway between points A and B;

and

(b) the velocity of the velocity pole, I. Using the instantaneous center of acceleration determine:

(c) the acceleration of the pole, I; and

(d) the accelerations of points A and C.
