2. MIL-S-901 - Wikipedia

   en.wikipedia.org/wiki/MIL-S-901

   Service C motors shall be marine type commercial motors. Service C motors shall meet the requirements of MIL-S-901 for Grade B shock. Service A motors. Service A for driven auxiliaries including propulsion, which are essential to the military effectiveness of a ship, should be heavy-duty, high impact, shock-resistant motors.

3. MacPherson strut - Wikipedia

   en.wikipedia.org/wiki/MacPherson_strut

   Honda introduced another variation strut set-up, called "dual-axis", which is used in the suspension design of the Civic Type-R. Another variant of the MacPherson strut is the double pivot front suspension, which splits the lower wishbone into two while retaining the standard upright design of the MacPherson strut.

4. Shock absorber - Wikipedia

   en.wikipedia.org/wiki/Shock_absorber

   A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction).

5. Active suspension - Wikipedia

   en.wikipedia.org/wiki/Active_suspension

   An active suspension is a type of automotive suspension that uses an onboard control system to control the vertical movement of the vehicle's wheels and axles relative to the chassis or vehicle frame, rather than the conventional passive suspension that relies solely on large springs to maintain static support and dampen the vertical wheel movements caused by the road surface.

6. Shaped charge - Wikipedia

   en.wikipedia.org/wiki/Shaped_charge

   Ames Laboratory translated this idea into a self-destroying shock tube. A 66-pound shaped charge accelerated the gas in a 3-cm glass-walled tube 2 meters in length. The velocity of the resulting shock wave was 220,000 feet per second (67 km/s). The apparatus exposed to the detonation was completely destroyed, but not before useful data was ...

7. Shock (mechanics) - Wikipedia

   en.wikipedia.org/wiki/Shock_(mechanics)

   Classical shock testing consists of the following shock impulses: half sine, haversine, sawtooth wave, and trapezoid. Pyroshock and ballistic shock tests are specialized and are not considered classical shocks. Classical shocks can be performed on Electro Dynamic (ED) Shakers, Free Fall Drop Tower or Pneumatic Shock Machines.

8. Shock (fluid dynamics) - Wikipedia

   en.wikipedia.org/wiki/Shock_(fluid_dynamics)

   Shock is an abrupt discontinuity in the flow field and it occurs in flows when the local flow speed exceeds the local sound speed. [1] More specifically, it is a flow whose Mach number exceeds 1. Explanation of phenomena

9. List of vacuum tubes - Wikipedia

   en.wikipedia.org/wiki/List_of_vacuum_tubes

   Better, often dual, getters were implemented to maintain a better vacuum, and more-rigid electrode supports introduced to reduce microphonics and improve vibration and shock resistance. The mica spacers used in "SQ" and "PQ" types did not possess sharp protrusions which could flake off and become loose inside the bulb, possibly lodging between ...
