Angle of Twist for Circular Shafts is the angular deformation along the length of a circular shaft subjected to torsion, measured in radians. And is denoted by θCircularshafts. Angle of Twist for Circular Shafts is usually measured using the Radian for Angle. Note that the value of Angle of Twist for Circular Shafts is always negative. Typically, the value of Angle of Twist for Circular Shafts is greater than 0.
