The uniform 200-kg bar AB is raised in the vertical plane by the application of a constant couple M = 3 kN·m applied to the link at C. The mass of the links is small and may be neglected. If the bar starts from rest at θ = 0, determine the magnitude of the force supported by the pin at A as the position θ = 60° is passed.
