The pressure angle in gears is defined as the angle between the line of action (which is the direction along which the force is transmitted between two meshing gears) and the common tangent to the pitch circles of the two gears in the plane of rotation. This angle is crucial in gear design as it affects the amount of force and the direction in which it is applied to the gear teeth, influencing the gear's efficiency and durability.
