The term is rotate. It is the point when the aircraft is at a speed that it can safely lift off and the pilot rotates the control column aft to make the plane climb. Source(s): Former USAF Aircrew.
Crazing is the phenomenon that produces a network of fine cracks on the surface of a material, for example in a glaze layer. Crazing frequently precedes fracture in some glassy thermoplastic polymers.razing occurs in some thermoplastics such as acrylonitrile butadiene styrene (ABS plastic) when stressed. It is a typical response in rubber toughening, where crazes are initiated at the surfaces of the rubber particles added to toughen the material.
GEL COAT CRAZINGS & SCRATCHES-Most cracks found on fiberglass boats are gel coat cracks commonly known as crazing. They can appear as a single line, a series of parallel lines, or a spider web originating at the center of an impact. It is caused by an impact or stress with enough force to crack the surface, but not the glass beneath. The gel coat forming the finish surface is pigmented resin about 15 thousands thick.
