Is Angle of Twist the Same as Degrees of Rotation in Beam Mechanics?

[wildleaf]

Homework Statement

is angle of twist and degrees rotation the same thing??

Homework Equations

(angle of twist is TL/JG, units are rad. Degrees roation is found by using moment and integrating moment equation once. to get EI dw/dx = integral of Moment + C1 ) (Units are unit-less but u say its degree)

Angle of twist is a rotation in the beam's centroidal axis due to torsion. Degrees of rotation how you described it (EI dw/dx) is a rotation of the beam from the horizontal due to deflection. It's not the same thing.
