Damper (flow) Opposed blade dampers in a mixing duct. A damper is a valve or plate that stops or regulates the flow of air inside a duct, chimney, VAV box, air handler, or other air-handling equipment. A damper may be used to cut off central air conditioning (heating or cooling) to an unused room, or to regulate it for room-by-room temperature ...
Shock absorbers are an important part of car suspension designed to increase comfort, stability and overall safety. The shock absorber, produced with precision and engineering skills, has many important features. The most common type is a hydraulic shock absorber, which usually includes a piston, a cylinder, and an oil-filled chamber.

Actuator. An actuator is a component of a machine that produces force, torque, or displacement, usually in a controlled way, when an electrical, pneumatic or hydraulic input is supplied to it in a system (called an actuating system ). [ 1] An actuator converts such an input signal into the required form of mechanical energy.
The graph shows the effect of a tuned mass damper on a simple spring–mass–damper system, excited by vibrations with an amplitude of one unit of force applied to the main mass, m 1. An important measure of performance is the ratio of the force on the motor mounts to the force vibrating the motor, F 0 / F 1 .
Dual-mass flywheel. A dual-mass flywheel ( DMF or DMFW) is a rotating mechanical device that is used to provide continuous energy ( rotational energy) in systems where the energy source is not continuous, the same way as a conventional flywheel acts, but damping any violent variation of torque or revolutions that could cause an unwanted vibration.
Damper winding. Bars and rings of the damper (amortisseur) winding of an AC generator (General Electric, early 20th century). Note the gaps in the cage along the quadrature axes. The damper winding (also amortisseur winding[ 1]) is a squirrel-cage -like winding on the rotor of a typical synchronous electric machine.
Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details ...
