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.
The causes of crazing include: Thermal expansion mis-match between the glaze and the body. Poor glaze/body fit is the main cause of crazing and can be due to: Under-firing resulting in failure to develop sufficient body thermal expansion. Firing too quickly, resulting in failure to achieve sufficient heatwork.
