The 24-kg uniform slender bar AB is mounted on end rollers of negligible mass and rotates about the fixed point O as it follows the circular path in the vertical plane. The bar is released from a position which gives it an angular velocity ω = 2 rad/s as it passes the position θ = 45°. Calculate the forces F_A and F_B exerted by the guide on the rollers for this instant.
