Members AB and BC shown in Fig. F-002(MM) are pinned together at point B, and are pinned to the floor at points A and C. The structure supports a pulley at point B with which, a person is hoisting a 2.0 kN load. Member BC has a weight of 1.6 kN, which may be considered to act at its center, while AB is made of strong-light material and has negligible weight. Determine the value of the external support reactions at A and C. 37 1 m 4 m MATHalino.com B 2.0 KN 1.6 KN Figure F-002(MM) 4 m MATHalino.com 45 C
