The 100-kg pendulum has a center of mass at G and a radius of gyration about G of k_G = 250 mm. Determine the horizontal and vertical components of reaction on the beam by the pin A and the normal reaction of the roller B at the instant θ = 90° when the pendulum is rotating at ω = 8 rad/s. Neglect the weight of the beam and the support.
