A horizontal beam of mass 90.2 kg and length 25.0 m rest on two supports A and B as shown. The distance between A and B is 10.0 m and the distance from C to A is 5.00 m. A person of mass 83.5 kg stands on the board a. If the person stands at point C, what are the forces the two supports exert on the board? b. If the person stands at point D, what are the forces the two supports exert on the board? c. Are either of the positions where the person stands (C or D) stable? Explain. C | A B D
