Wheelchair ramp, Hotel Montescot, Chartres, France Demonstration inclined plane used in education, Museo Galileo, Florence.. An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle from the vertical direction, with one end higher than the other, used as an aid for raising or lowering a load.
The tables below have been calculated using a heat capacity ratio, , equal to 1.4. The upstream Mach number, M 1 {\displaystyle M_{1}} , begins at 1 and ends at 5. Although the tables could be extended over any range of Mach numbers, stopping at Mach 5 is typical since assuming γ {\displaystyle \gamma } to be 1.4 over the entire Mach number ...
A concrete wheelchair ramp A portable wheelchair ramp. A wheelchair ramp is an inclined plane installed in addition to or instead of stairs.Ramps permit wheelchair users, as well as people pushing strollers, carts, or other wheeled objects, to more easily access a building, or navigate between areas of different height.
The ramp function is a unary real function, whose graph is shaped like a ramp. It can be expressed by numerous definitions, for example "0 for negative inputs, output equals input for non-negative inputs". The term "ramp" can also be used for other functions obtained by scaling and shifting, and the function in this article is the unit ramp ...
as a ratio of one part rise to so many parts run. For example, a slope that has a rise of 5 feet for every 1000 feet of run would have a slope ratio of 1 in 200. (The word "in" is normally used rather than the mathematical ratio notation of "1:200".) This is generally the method used to describe railway grades in Australia and the UK.
RTI ramp Modified Jeep ramping an RTI ramp Ramp travel index or RTI, is a way of measuring a vehicle's ability to flex its suspension, a property also known as axle articulation. The RTI rating is used mainly in the off-roading industry to test and describe chassis limits of modified vehicles.
The typical height of a vert ramp is 11 ft (3.4 m) to 14 ft (4.3 m) with anywhere from 6 in (150 mm) to 2 ft (0.61 m) of vertical on top. Vert skating ramps can be made with 6 in (150 mm) to 1 ft (0.30 m) of vertical while vert skateboarding ramps are typically made with 1ft to 2 ft (0.61 m) of vertical in order for the skateboard to launch ...
The equivalent piecewise linear functions = ⌊ ⌋ = based on the floor function of time t is an example of a sawtooth wave with period 1. A more general form, in the range −1 to 1, and with period p , is 2 ( t p − ⌊ 1 2 + t p ⌋ ) {\displaystyle 2\left({\frac {t}{p}}-\left\lfloor {\frac {1}{2}}+{\frac {t}{p}}\right\rfloor \right)}
