Floor slip resistance testing is the science of measuring the coefficient of friction (or resistance to slip accidents) of flooring surfaces, either in a laboratory (before or after installation) or on floors in situ. Slip resistance testing (or floor friction testing) is usually desired by the building's owner or manager when there has been a ...
Road slipperiness. A surface friction tester, used to measure road slipperiness. Road slipperiness is a condition of low skid resistance due to insufficient road friction. It is a result of snow, ice, water, loose material and the texture of the road surface on the traction produced by the wheels of a vehicle. [1]
An anti-lock braking system ( ABS) is a safety anti- skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses. [ 1] ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over ...
A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process. In the process industry, a standard set of symbols is used to prepare drawings of processes. The instrument symbols used in these drawings are generally based on ...
Skid marks from aircraft tires on a runway. A skid mark is the visible mark left by any solid which moves against another, and is an important aspect of trace evidence analysis in forensic science and forensic engineering. Skid marks caused by tires on roads occur when a vehicle wheel stops rolling and slides or spins on the surface of the road.
A Formula Student car performing a skidpad test. (2009) A skidpad or skidpan is a circular area of flat pavement used for various tests of a car's handling. The most common skidpad use is testing lateral acceleration, measured in meters per second squared (m/s 2) or the scaled unit g-force. This usage has similarities to that of using a kick plate.
In hydrogeology, an aquifer test (or a pumping test) is conducted to evaluate an aquifer by "stimulating" the aquifer through constant pumping, and observing the aquifer's "response" ( drawdown) in observation wells. Aquifer testing is a common tool that hydrogeologists use to characterize a system of aquifers, aquitards and flow system boundaries.
YORK, Pa. (AP) — Authorities say seven firefighters were injured when two tanker trucks crashed while responding to a large blaze in York, Pennsylvania. Officials said the crash occurred shortly ...
