Gears A and B are fixed, while gears C and D are free to rotate about the shaft S. If the shaft turns about the z axis at a constant rate of w = 5 rad/s, determine the angular acceleration of gear C. 0 mm 80 mm Select one: O a. a = 32i rad/s? O b. a = 67i rad/s? O c. a = 76i rad/s2 o d. a = 40i rad/s2
