Wheel alignment, which is sometimes referred to as breaking or tracking, is part of standard automobile maintenance that consists of adjusting the angles of wheels to the car manufacturer specifications. [1] The purpose of these adjustments is to reduce tire wear and to ensure that vehicle travel is straight and true (without "pulling" to one ...
A coordinate system used for tire analysis by Pacejka and Cossalter. The origin is at the intersection of three planes: the wheel midplane, the ground plane, and a vertical plane aligned with the axle (not pictured).
When a wheel is set up to have some camber angle, the interaction between the tire and road surface causes the wheel to tend to want to roll in a curve, as if it were part of a conical surface (camber thrust). This tendency to turn increases the rolling resistance as well as increasing tire wear. A small degree of toe (toe-out for negative ...
On the inside, new blue seats were installed to match the new 7000-series cars. A dozen 6000-series and 3000-series cars received these features. WMATA says repainting would cost $14,055 per car, while implementing a vinyl wrap costs only $4,776.

Another way to create printer-friendly web pages is to use a CSS style sheet. A CSS style sheet is a set of instructions that tell the web browser how to display a web page . By using a separate style sheet specifically for printing , a web page can be laid out to fit on an 8.5"x11" or A4 sheet.
In modern browsers, the print function of the browser should automatically use the rules in the style sheets when you print an article, therefore the print command of your web browser is also useful. Certain page elements normally do not print; these include self references like section edit links, navigation boxes, message boxes and metadata. [1]
