Technician A says output torque is decreased and output speed is increased when a large gear drives a smaller gear. Technician B says output torque is increased and output speed is decreased when a small gear drives a larger gear. Who is correct?
A)A only
B)B only
C)Both A and B
D)Neither A nor B

Both statements are correct. When a large gear drives a smaller gear, the output speed increases but the torque decreases. Conversely, when a small gear drives a larger gear, the output torque increases while the output speed decreases. This is due to the mechanical advantage and gear ratio principles.
