For example, soft rubbers often provide better traction but also wear faster and have higher losses when flexed—thus reducing efficiency. Choices in material selection may have a dramatic effect. For example: tires used for track racing cars may have a life of 200 km, while those used on heavy trucks may have a life approaching 100,000 km.
The classic reproduction methods involved blue and white appearances (whether white-on-blue or blue-on-white), which is why engineering drawings were long called, and even today are still often called, "blueprints" or "bluelines", even though those terms are anachronistic from a literal perspective, since most copies of engineering drawings ...

Technical drawing, drafting or drawing, is the act and discipline of composing drawings that visually communicate how something functions or is constructed. Technical drawing is essential for communicating ideas in industry and engineering .
Traction (mechanics), adhesive friction or force; Traction vector, in mechanics, the force per unit area on a surface, including normal and shear components; Traction motor, an electric motor used for propulsion of a vehicle, for example a car or a locomotive; Railway electric traction, the use of electric motors to propel rail cars

The term tractive effort is often qualified as starting tractive effort, continuous tractive effort and maximum tractive effort.These terms apply to different operating conditions, but are related by common mechanical factors: input torque to the driving wheels, the wheel diameter, coefficient of friction (μ) between the driving wheels and supporting surface, and the weight applied to the ...
A drawing which based on the detailed drawing, installation drawing or co-ordination drawing (interface drawing) with the primary purpose of defining that information needed by the tradesmen on site to install the works or concurrently work among various engineering assembly. The main features of typical installation drawings are:
