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 0 0, determine the magnitude of the force supported by the pin at A as the position 0 = 60 is passed. 0.5 1.75 0.75 m m B M D C 1.5 m 1.5 m
