Crashed car. Vehicle extrication is the process of removing a patient from a vehicle which has been involved in a motor vehicle collision. [1] Patients who have not already exited a crashed vehicle may be medically (cannot exit a vehicle due to their injuries) or physically trapped, [2] and may be pinned by wreckage, or unable to exit the vehicle because a door will not open.
The section lift coefficient is based on two-dimensional flow over a wing of infinite span and non-varying cross-section so the lift is independent of spanwise effects and is defined in terms of ′, the lift force per unit span of the wing. The definition becomes
A check sheet is a form (document) used to collect data in real time at the location where the data is generated. The data it captures can be quantitative or qualitative. When the information is quantitative, the check sheet is sometimes called a tally sheet. [1] The check sheet is one of the so-called Seven Basic Tools of Quality Control. [2]
In general, a checklist is a quality management tool, an aid to completing a complex task correctly and completely. It is an aid to recall, provides a reminder of the correct sequence, and uses the operator's knowledge and skill efficiently to ensure that no critical steps are omitted, even when the operator is under stress or has degraded attention due to fatigue or other distractions, It ...
The Peterborough Lift Lock is a boat lift located on the Trent Canal in the city of Peterborough, Ontario, Canada, and is Lock 21 on the Trent-Severn Waterway. For many years, the lock's dual lifts were the highest hydraulic boat lifts in the world, raising boats 65 ft (20 m).
Lift-induced drag, induced drag, vortex drag, or sometimes drag due to lift, in aerodynamics, is an aerodynamic drag force that occurs whenever a moving object redirects the airflow coming at it. This drag force occurs in airplanes due to wings or a lifting body redirecting air to cause lift and also in cars with airfoil wings that redirect air ...
The lift and the drag forces, L and D, are scaled by the same factor to get C L and C D, so L/D = C L /C D. L and D are at right angles, with D parallel to the free stream velocity (the relative velocity of the surrounding distant air), so the resultant force R lies at the same angle to D as the line from the origin of the graph to the ...
In data mining and association rule learning, lift is a measure of the performance of a targeting model (association rule) at predicting or classifying cases as having an enhanced response (with respect to the population as a whole), measured against a random choice targeting model.
