1. The problem statement, all variables and given/known data A pendulum has a mass of 7.5 kg with a center of mass at G (radius=250mm) and hass a radius of gyration about the pivot O of 295 mm. If the pendulum is released from rest at theta=0º, determine the total force supported by the bearing at the instant when theta=60º. Friction in the bearing is considered negligible 2. Relevant equations At-Wsin(theta)=mr(alpha) An-Wcos(theta)=mr(omega)^2 rAt=mk^2(alpha) k=radius of gyration At=tangential acceleration An=normal acceleration 3. The attempt at a solution I´m stuck. I know there has to be some relation between the moment of inertia and the acceleration but I don´t know how to solve this.
