Final answer:
The circle for direct transfer of speed and torque is called the pitch circle. When torque is increased on Gear A, the angular velocity of Gear B increases.
Step-by-step explanation:
The circle along which speed and torque are directly transferred is called the pitch circle. The subject at hand is related to gears and their mechanical properties. When gear A, which turns clockwise, meshes with gear B, which turns counterclockwise, any increase in force applied to gear A which creates more torque, will consequently alter the angular velocity of gear B. If gear A applies more torque to gear B, the angular velocity of gear B will increase in magnitude. Torque, as a concept, is the rotational equivalent of a force and is critical in determining the twisting effectiveness on a system.
