Static stability is the ability of a robot to remain upright when at rest, or under acceleration and deceleration Static stability may also refer to: In aircraft or missiles: Static margin — a concept used to characterize the static stability and controllability of aircraft and missiles.
Three cases for static stability: following a pitch disturbance, aircraft can be unstable, neutral, or stable. If an aircraft is longitudinally statically stable, a small increase in angle of attack will create a nose-down pitching moment on the aircraft, so that the angle of attack decreases.
is the static margin and must be negative for longitudinal static stability. Alternatively, positive angle of attack must generate positive yawing moment on a statically stable missile, i.e. must be positive. It is common practice to design manoeuvrable missiles with near zero static margin (i.e. neutral static stability).
Posturography is the technique used to quantify postural control in upright stance in either static or dynamic conditions. Among them, Computerized dynamic posturography (CDP), also called test of balance (TOB), is a non-invasive specialized clinical assessment technique used to quantify the central nervous system adaptive mechanisms (sensory, motor and central) involved in the control of ...
Static stability: minimum distance from the center of mass (COM) to any edge of the support polygon created by the legs in stance for each moment in time. [13] A walking animal is statically stable if there are enough legs to form the support polygon (i.e. 3 or more) and the COM is within the support polygon.
Limits of Stability (LoS) is a significant variable in assessing stability and voluntary motor control [6] in dynamic states. [7] It provides valuable information by tracking the instantaneous change in the center of mass (COM) velocity and position. [7]
Static lung compliance is the change in volume for any given applied pressure. [1] Dynamic lung compliance is the compliance of the lung at any given time during actual movement of air. Low compliance indicates a stiff lung (one with high elastic recoil ) and can be thought of as a thick balloon – this is the case often seen in fibrosis .
Even while training at a lower intensity (training loads of ≈20-RM), anaerobic glycolysis is still the major source of power, although aerobic metabolism makes a small contribution. [48] Weight training is commonly perceived as anaerobic exercise, because one of the more common goals is to increase strength by lifting heavy weights.
