Abstract
Twist control system and method for controlling twisting distortion in a beam caused by temperature changes. In a beam having an inherent amount of temperature induced twisting a wrap can be helically bonded to the beam. The wrap has a wrap material type, a wrap cross-sectional profile, and a wrap angle that can be selectively chosen for providing a desired twist control of the beam. The twist control applies a twisting force to the beam which is approximately proportional to the temperature change. The twist control can be used to eliminate the thermally induced twist associated with a particular beam or for providing a desired amount of twist.
