a light aluminum piston is attached to the spindle of the instrument and is arranged to move in a fixed air chamber closed at one end which is may be circular or rectangular. compression and suction action of piston on the air in chamber damp the possible oscillation of the deflecting element.

Is friction useful with computers?
No Friction Runes Computers
How is it possible to hit a golf ball on the moon?
It works the same way it does on Earth. The momentum of the club is transferred to the golf ball and it travels. And it isn't slowed down by the friction of air.
How is friction applied?
Friction is applied, by making the surface of whatever you want to slide across it (the thing you want to apply friction to) is really rough. You can inscrease, and decrease the amount of friction acting on an object by changing the texture, material and smoothness of the surface. Smoother surfaces don't apply much friction to objects, and rougher surfaces apply a lot. An example of this, is Wellington Boots. They have rough underneaths, so you don't fall over - they apply a lot of friction.
What is over damping?
Overdamping occurs when the system achieves the desired result without overshooting, but takes longer than necessary to do so, as the critical elements require a slower response time.
What two types of energy do you get from friction?
thermal, and kinetic
What are the different methods of damping used in analog indicating instruments?
Damping torque can be provided by: (a) air friction damping (b) fluid friction damping (c) eddy current damping. In air friction damping, a light piston moves with a very small clearance in air chamber. The piston moves against pressure of air in air chamber. In fluid friction damping, light varies are attached to spindle of moving system. The movement of spindle is suppressed due to fluid friction, Eddy current damping is one of the most efficient method of damping. It is based on the principle that whenever a sheet of conducting but non magnetic material like copper or aluminum moves in magnetic field, eddy currents are induced.
How many types of damping torque in moving instruments?
air friction ,fluid friction, eddy current
How can you decrease the degree of damping?
You can decrease the degree of damping by reducing the amount of friction or resistance in the system. This can be achieved by using lighter weight damping materials, adjusting the damping coefficients, or using a less viscous damping fluid.
When damping is occur in the system?
Damping occurs in a system when energy is dissipated and the amplitude of the oscillations gradually decreases over time. This can be due to factors such as friction, air resistance, or material properties absorbing the energy of the system. Damping helps stabilize the system and prevent it from oscillating indefinitely.
Why damping causw decrease in the amplitude of a vibration?
Damping in a vibrating system causes a decrease in amplitude because it dissipates energy from the system in the form of heat or sound. As energy is lost to damping forces such as friction or air resistance, the system's natural frequency is reduced, leading to smaller oscillations over time.
What is damping coefficient of a pendulum?
The damping coefficient of a pendulum is a measure of how quickly the pendulum's oscillations dissipate over time due to external influences like air resistance or friction. A larger damping coefficient means the pendulum's motion will decay more rapidly, while a smaller damping coefficient means the motion will persist longer. The damping coefficient is typically denoted by the symbol "b" in the equation of motion for a damped harmonic oscillator.
When referring to mechanical terms what is damping?
Damping in mechanical terms means that there is a reduction in the amplitude of oscillation because the energy is being drained. The system is trying to to stop friction.
Why does sound get quieter?
Because of air damping.
What is the derivation of the damped pendulum equation and how does it describe the motion of a pendulum with damping effects?
The damped pendulum equation is derived from Newton's second law of motion and includes a damping term to account for the effects of air resistance or friction on the pendulum's motion. This equation describes how the pendulum's oscillations gradually decrease in amplitude over time due to the damping effects, resulting in a slower and smoother motion compared to an undamped pendulum.
How does surface area affect damping of an oscillation?
Increasing the surface area of an object can lead to increased air resistance, which in turn can increase the damping of an oscillation. This is because the increased air resistance absorbs more energy from the oscillation, causing it to lose its amplitude faster. Therefore, objects with larger surface areas tend to experience greater damping of their oscillations.
How are air resistance and friction alike?
Air resistance is a type of fluid friction (along with water resistance) and is therefore is a type of friction.
Air that resist movement or returns to its original position after an initial vertical displacement is called?
stable air
