A wooden frame is in equilibrium with the support A and three external forces, where the concentrated force F = 100 N, and the density of the distributed force is W = 150 N/m. the direction angles are given as a = 25 and = 30. Neglect the thickness of the members. a. Draw the Free-body Diagram of the frame and identify ALL unknown forces. [8 marks] b. Write the equations for the equilibrium state of the frame, as well as calculate the tension force in cable BC and the reactions at support A. 3m 4 m B -4.5 m- W 1 F [12 marks]
