Q factor for a series resonant circuit (RL circuits)

It is defined as the peak energy stored in the circuit divided by the average energy dissipated in it per cycle at resonance; Q factor is directly ... more

Mechanical Efficiency (pumps)

Mechanical components – as transmission gear and bearings – generates a mechanical loss that reduces the power transferred from the motor shaft ... more

Hawking Radiation - Temperature of a black body (or a black hole)

A black body is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. A black hole ... more

Fractional bandwidth (RLC circuits)

The bandwidth as a fraction of the resonance frequency. Bandwidth is the difference between the upper and lower frequencies in a continuous set of ... more

Electric Motor's efficiency

The electric motor’s efficiency is the mechanical output power divided by the electrical input power

Regenerative brake (KERS Flywheel energy)

A regenerative brake is an energy recovery mechanism which slows a vehicle or object by converting its kinetic energy into a form which can be either used ... more

Damping factor (RLC circuit)

Damping is an influence within or upon an oscillatory system that has the effect of reducing, restricting or preventing its oscillations.( The neper ... more

Torque on a current-carring loop

When current is passed through the loops, the magnetic field exerts torque on the loops, which rotates a shaft. Electrical energy is converted to ... more

Cyclotron resonance frequency

A cyclotron is a type of particle accelerator in which charged particles accelerate outwards from the center along a spiral path. The particles are held to ... more

Tractive Force

As used in mechanical engineering, the term tractive force can either refer to the total traction a vehicle exerts on a surface, or the amount of the total ... more
