Yes, "beat" is an action verb. It describes an action typically involving striking or defeating someone or something. For example, in the sentence "She beat the drum," "beat" indicates the action of striking the drum.
"to tap"
Self-servo action: Is where a leading shoe is effectively self applied to the drum. During rotation of the tyre, the leading shoe tries to rotate in the direction of the drum and then forms a wedge and eventually effectively applying itself to the drum. I guess that's the best answer you can get
It is the action of the Brake shoe which increases due ti the direction of the rotation It is the action of the Brake shoe which increases due ti the direction of the rotation Self servo action: As the drum rotates the leading shoe wedges against the drum causing the trailing shoe to make contact.

When the brake cylinder pushes the two shoes apart, the leading shoe "wraps" with the rotating drum. This wrapping pushes the trailing shoe through the transfer bar into tighter contact with the drum providing the servo action.Notice that your leading shoe nearly always has more brake lining than the trailing shoe and also notice that it requires more pedal effort to stop a car with drum brakes when it is going in reverse than it does when the car is moving the same speed in the forward direction.
A drum roller dryer works by rotating a drum that is heated from the inside. As wet materials are fed into the drum, the heat evaporates the moisture, and the rotating action helps to evenly distribute the heat, resulting in efficient drying of the materials.
A percussion instrument is any instrument in which the sound is achieved by a striking action (thus the name 'percussion'). The steel drum is struck with rubber mallets to produce the tone, and different spots in a drum correspond to different notes. The bigger the spot, the lower the tone.
Duo-servo type drum brakes are an improved version of twin leading construction, where two brake shoes are linked. When a primary side leading shoe is pressed against the drum by the wheel cylinder, the force that makes it rotate together with the drum wedges the secondary side leading shoe into the drum to achieve braking action. This type of drum brake provides strong braking for both forward and reverse movement. It is used in commercial vehicles that require especially large braking forces.
It is the metal part around the outside of the drum that is around the drum head.
