Effective ship installations require rotors having a weight of approximately 3% to 5% of a vessel's displacement. Unlike hydrodynamic roll stabilizing fins, the ship gyroscopic stabilizer can only produce a limited roll stabilizing moment that may be exceeded as the wave height increases.
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]
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 ...
Diagram of retractable fin stabilizers on a ship. Ship stabilizers: a fixed fin stabilizer (foreground centre) and bilge keels (left background).. Ship stabilizers (or stabilisers) are fins or rotors mounted beneath the waterline and emerging laterally from the hull to reduce a ship's roll due to wind or waves.
The Buckau, the first vehicle to be propelled by a Flettner rotor. A Flettner rotor is a smooth cylinder with disc end plates which is spun along its long axis and, as air passes at right angles across it, the Magnus effect causes an aerodynamic force to be generated in the direction perpendicular to both the long axis and the direction of airflow.

Once the brake pads make contact with the rear wheel, the Slidepad slides forward, which pulls a cable that is connected to the front brakes. [1] Similar to the anti-lock brake system in cars, the mechanism prevents the front wheel from locking, no matter how hard the brake is pressed or how slippery the road conditions are.
Army project manager and fitness trainer SFC Scott Dalrymple shares his part in the military's fitness plan "to help soldiers and make them better war-fighters" on "The Ingraham Angle."
Counter-rotating propellers World War I Linke-Hofmann R.I German heavy bomber (1917) with counter-rotating propellers He 177A Greif with counter-rotating propellers. Counter-rotating propellers (CRP) are propellers which turn in opposite directions to each other. [1]
