2. Brake pad - Wikipedia

   en.wikipedia.org/wiki/Brake_pad

   The brake pad and disc (now both having the friction material), then "stick" to each other, providing the friction that stops the vehicle. In disc brakes, there are usually two brake pads per disc rotor, they both function together. These are held in place and actuated by a caliper affixed to the wheel hub or suspension upright. Racing calipers ...

3. Regenerative braking - Wikipedia

   Mechanism for regenerative brake on the roof of a Škoda Astra tram The S7/8 Stock on the London Underground can return around 20% of its energy usage to the power supply. [ 1 ] Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy or potential energy into a form that ...

4. Disc brake - Wikipedia

   en.wikipedia.org/wiki/Disc_brake

   On automobiles, disc brakes are often located within the wheel A drilled motorcycle brake disc. The development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated similarly to a modern disc-brake system even though the disc was thin and a cable activated the brake pad. [4]

5. Rotary encoder - Wikipedia

   en.wikipedia.org/wiki/Rotary_encoder

   At the top, the housing, interrupter disk, and light source can be seen; at the bottom the sensing element and support components. A rotary encoder , also called a shaft encoder , is an electro-mechanical device that converts the angular position or motion of a shaft or axle to analog or digital output signals.

6. Disk loading - Wikipedia

   en.wikipedia.org/wiki/Disk_loading

   Disk loading of a hovering helicopter is the ratio of its weight to the total main rotor disk area. It is determined by dividing the total helicopter weight by the rotor disk area, which is the area swept by the blades of a rotor.

7. Bicycle brake - Wikipedia

   en.wikipedia.org/wiki/Bicycle_brake

   Light use of the rear brake causes a light skid as the bicycle approaches the limit where pitchover will occur, a signal to reduce force on the front brake. On a low-traction surface or when turning, the front wheel will skid, the bicycle cannot be balanced and will fall to the side instead.
