The Steel And Foam Energy Reduction Barrier (SAFER Barrier), sometimes generically referred to as a soft wall, is a technology found on oval automobile race tracks and high-speed sections of road and street tracks, intended to absorb and reduce kinetic energy during the impact of a high-speed crash, and thus, lessen injuries sustained to ...
A fat tire is a type of wide oversized bicycle tire, typically 3.8 in (97 mm) or larger and rims 2.6 in (66 mm) or wider, designed for low ground pressure to allow riding on soft unstable terrain, such as snow, sand, bogs, and mud. [70]

[2] These are cantilevered from a footing and rise above the grade on one side to retain a higher level grade on the opposite side.
An example of lateral earth pressure overturning a retaining wall. The lateral earth pressure is the pressure that soil exerts in the horizontal direction. It is important because it affects the consolidation behavior and strength of the soil and because it is considered in the design of geotechnical engineering structures such as retaining walls, basements, tunnels, deep foundations and ...
The term is used with buildings and non-building structures to identify when a wall or element is intentionally built with an inward slope. A battered corner is an architectural feature using batters. A batter is sometimes used in foundations, retaining walls, dry stone walls, dams, lighthouses, and fortifications.
