5. (12 points, partial credit) A sandwich board advertising sign is constructed as shown. The sign's mass is 8.00 kg. Calculate the tension in the chain assuming no friction between the legs and the sidewalk. Hinge 1.10 m Chain Problem 9-14 CG CG It is only necessary to analyze the equilibrium of one-half of the structure. We analyze the left leg. From symmetry, it can be deduced that the force the hinge gives to the left leg, FH (assumed positive quantity and points to left), must be horizontal. 0.800 m Uniform board (cG at center) 0.70 m
