Dual-pivot steering geometry (also known as virtual pivot) is a geometric arrangement of linkages in the steering of a car designed to reduce or eliminate scrub radius by moving the pivot point of the king pin outboard, in order to improve steering precision and straight line stability.
Vehicle size classes are series of ratings assigned to different segments of automotive vehicles for the purposes of vehicle emissions control and fuel economy calculation. . Various methods are used to classify vehicles; in North America, passenger vehicles are classified by total interior capacity while trucks are classified by gross vehicle weight rating (GV
A security checkpoint in Nepal, established to check for Maoist insurgents, during the Nepalese Civil War. The unit establishing a military checkpoint must carry or obtain the materials necessary to construct it. It might use a large vehicle, or multiple vehicles, such as armored personnel carriers to block the road.
The most commonly used size is about six and a half feet long, and carries a load of 1,000 pounds (450 kg). However, "the largest chukudus can carry up to 800 kilograms (1,800 lb)." [ 9 ] Some chukudus are equipped with suspension to the front wheel, either in the form of a metal spring or of tensioned rubber bands.
Modern cars do not use pure Ackermann steering, partly because it ignores important dynamic and compliant effects, but the principle is sound for low-speed maneuvers. Some racing cars use reverse Ackermann geometry to compensate for the large difference in slip angle between the inner and outer front tires while cornering at high speed.
Vehicle interior ergonomics are integral to an automotive design education. The Society of Automotive Engineers (SAE) has adopted tools for vehicle design, including statistical models for predicting driver eye location and seat position as well as an H-point mannequin for measuring seats and interior package geometry. See SAE J826 for a ...
A control point (CP, also control and checkpoint) is a marked waypoint used in orienteering and related sports such as rogaining and adventure racing. It is located in the competition area; marked both on an orienteering map and in the terrain, and described on a control description sheet. The control point must be identifiable on the map and ...
A fourth generation Chevrolet Caprice hi-riser. This model Caprice is commonly known by the term "bubble" due to its rounded style. Hi-risers are a type of heavily-customized automobile, typically a full-size, body-on-frame, rear-wheel drive American sedan.
