Slope is used to construct wheelchair ramps, roads and stairs, according to the University of Regina's Math Central website. Slope is a way of describing the steepness of an object.
Slope is very important in the construction field because it often dictates the best way to complete a project. Special building materials are used for low-slope roofs, so a construction worker must know the slope of the roof before beginning a shingling project. The slope of a road affects water runoff, so civil engineers and construction workers must plan accordingly. Most municipalities have rules regarding the minimum slope of their roads.
Skiing enthusiasts pay special attention to the slopes of their favorite trails. The greater the slope of a trail, the more challenging it is. Knowing the slope of a particular trail makes it easier for skiers to judge the danger of skiing on that trail.
Slope is also important to people who use wheelchairs. If a wheelchair ramp is too steep, it may be difficult to use. Constructing a ramp with the right slope is especially important for people who use manual wheelchairs instead of power wheelchairs. If a ramp is too steep, the user may not have the upper arm strength necessary to power a manual chair up the ramp.
