2. Drum brake - Wikipedia

   en.wikipedia.org/wiki/Drum_brake

   Drum brake (upper right) with the drum removed (lower left, inside facing up), on the front of a Ford Falcon Sprint A rear drum brake on a Kawasaki W800 motorcycle. A drum brake is a brake that uses friction caused by a set of shoes or pads that press outward against a rotating bowl-shaped part called a brake drum.

3. Wheel cylinder - Wikipedia

   en.wikipedia.org/wiki/Wheel_cylinder

   Some designs use two single piston wheel cylinders, one at the top of the drum and one at the bottom, each connected to one brake shoe. [3] Wheel cylinders must be rebuilt or replaced if they show signs of leaking. Wheel cylinders used to be made of cast iron. However, they were more prone to rusting and aluminium is now the preferred material.

4. Aluminium alloy - Wikipedia

   en.wikipedia.org/wiki/Aluminium_alloy

   Welded aluminium alloy bicycle frame, made in the 1990s. An aluminium alloy (UK/IUPAC) or aluminum alloy (NA; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc.

5. Bicycle brake - Wikipedia

   en.wikipedia.org/wiki/Bicycle_brake

   Most bicycle brake systems consist of three main components: a mechanism for the rider to apply the brakes, such as brake levers or pedals; a mechanism for transmitting that signal, such as Bowden cables, hydraulic hoses, rods, or the bicycle chain; and the brake mechanism itself, a caliper or drum, to press two or more surfaces together in ...

6. Eddy current brake - Wikipedia

   en.wikipedia.org/wiki/Eddy_current_brake

   Disk electromagnetic brakes are used on vehicles such as trains, and power tools such as circular saws, to stop the blade quickly when the power is turned off.A disk eddy current brake consists of a conductive non-ferromagnetic metal disc attached to the axle of the vehicle's wheel, with an electromagnet located with its poles on each side of the disk, so the magnetic field passes through the ...

7. 7050 aluminium alloy - Wikipedia

   en.wikipedia.org/wiki/7050_aluminium_alloy

   Aluminium 7050 alloy is a heat treatable alloy. It has high toughness, high strength. It has high stress corrosion cracking resistance. [1] It has electric conductivity of value having 40 percent of copper. [2] 7050 aluminium is known as a commercial aerospace alloy. [3]

8. Aluminium–copper alloys - Wikipedia

   en.wikipedia.org/wiki/Aluminium–copper_alloys

   The name is mainly used in pop-science to describe all Al-Cu alloys system. Aluminium–copper alloys were standardised in the 2000 series by the international alloy designation system (IADS) which was originally created in 1970 by the Aluminum Association. 2000s series includes 2014 and 2024 alloys used in airframe fabrication.

9. Aluminium–scandium alloys - Wikipedia

   en.wikipedia.org/wiki/Aluminium–scandium_alloys

   Aluminium–scandium alloys (AlSc) are aluminum alloys that consist largely of aluminium (Al) and traces of scandium (Sc) as the main alloying elements.In principle, aluminium alloys strengthened with additions of scandium are very similar to traditional nickel-base superalloys in that both are strengthened by coherent, coarsening resistant precipitates with an ordered L1 2 structure.
