    Converting torque to angular acceleration in rotational dynamics

    Question 1: T = mg(a+0.5c)costheta = I alpha ( a is the length in the picture ) mg(a+0.5c0costheta = 5 x 9.81 x cos(30) = 27.61 N m I = (1/12)m(b^2+c^2) + mr^2= (1/12) x 5 x (0.2^2 + 0.3^2) + 5 (0.65)^2 = 2.167 kg m^2 Alpha = 12.744 rad/s^2 Atangential = alpha x r = 12.744 x 0.65 = 8.283...

    Converting torque to angular acceleration in rotational dynamics

    Homework Statement Can someone help me those 2 questions Homework Equations I don't understand how to convert to angular acceleration The Attempt at a Solution I attempted of finding the torque due to gravity then divided it by the radius for the second question, I got it wrong...
