design model: consists of design geometry; can be 2d or 3d; typically has a black background.

design files: drawing created with microsoft expression design, a drawing and design program for windows; may contain both vector and raster graphics; can also include multiple layers and various image effects.

elements: an element is a single part of a larger group.

answer:

Power braking's benefits

Among the big advantages of a power braking system are it's: Regarded as safer. The heat caused by the friction of drum brakes causes them to wear down. Because disc brake systems have better heat distribution, they're more efficient
