Homework Help: Angle of Twist and Rotation

  1. Jul 12, 2011 #1
    1. The problem statement, all variables and given/known data

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

    2. Relevant 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)

    3. The attempt at a solution

    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.
