Shock - AMBOSS

Feb 01, 2021Summary. Shock is a life-threatening circulatory disorder that leads to tissue hypoxia and a disturbance in microcirculation.There are many different causes of shock, which are classified into hypovolemic shock (e.g., following massive blood/fluid loss), cardiogenic shock (e.g., as a result of acute heart failure), obstructive shock (e.g., due to cardiac tamponade), and distributive shock (due Failure analysis of shock absorber tubes ScienceDirectShock Absorber Working Principle , Types , FunctionIn addition to its mounting flexibility, mono-tube shocks are a significant component, along with the spring, in supporting vehicle weight. Another difference you may notice is that the mono-tube shock absorber does not have a base valve. Instead, all of the control during compression and extension takes place at the piston. mono tube shock Failure analysis of shock absorber tubes ScienceDirectShock Strut - Aircraft Landing Gear Systems Aircraft SystemsMany different designs of shock struts can be found in aircraft. Pneumatic/hydraulic shock strut referred to as an air/oil or oleo strut. A shock strut is constructed of two telescoping cylinders or tubes. Nose gear shock struts locating cam assembly keep the gear aligned. Nose gear shock struts have attachments for the installation of an external shimmy damper.
