Homework Help: Kinematics of rigid rotor - angular acceleration

  1. Apr 25, 2016 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution


    My question is why the answer of question 15.258 (a) about the angular acceleration of rod BD isn't correct.
    I used the realtion of tan(25) in the end of the solution.

    Please explain your reasoning.

    Is my equations are ok and you are only asking about the final equation with tan(25) and the t component and the n component?
