1. (40%) Fig. 1 depicts the model of a coaster wheel. (1) If the velocity of point A is Va, the angular velocity wi = +10 deg/s (j) is constant, and there is no wheel slip, determine the velocity of point B and C and the angular velocity 2. (2) Continuing from (1), determine the acceleration of point B and C. (3) Suppose that the velocity and acceleration of point A are Vaand aa, the change rate of the angular velocity wi is aa= +2 deg/s (), and there is no wheel slip, determine the velocity and acceleration of point C. (4) Continuing from (3), determine the angular acceleration of the disk. Y А Z 140 mm Х B 75 mm C 120 mm D Fig. 1
