2. Dissymmetry of lift - Wikipedia

   en.wikipedia.org/wiki/Dissymmetry_of_lift

   The dissymmetry of lift of one rotor disc is cancelled by the dissymmetry of lift of the other rotor disc. [citation needed] Tandem rotor helicopters such as the CH-47 Chinook still suffer from dissymmetry of lift, because the rotors are offset from one another. Tandem-rotor helicopters are installed with automatic cyclic feathering systems.

3. Brake pad - Wikipedia

   en.wikipedia.org/wiki/Brake_pad

   When the brakes are hydraulically applied, the caliper clamps or squeezes the two pads together onto the spinning rotor to slow and stop the vehicle. When a brake pad heats up due to contact with the rotor, it transfers small amounts of its friction material onto the disc, leaving a dull grey coating on it. The brake pad and disc (now both ...

   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]

   Linkages (silver) to the rotor blade In aeronautics , a swashplate is a mechanical device that translates input via the helicopter flight controls into motion of the main rotor blades . Because the main rotor blades are spinning, the swashplate is used to transmit three of the pilot's commands from the non-rotating fuselage to the rotating ...
