Unformatted text preview: (c) Draw free body diagrams for bars AB and BC, under the largest force F from (b). (10) C B A 3. See figure below. A beam AB is subjected to a concentrated force and a distributed load. Neglect the weight of the beam. (a) Find the reactions at the fixed support A. (5) (b) Find the internal shear force and bending moment at a section 2 m to the right of A. (10) (c) Draw the shear force and bending moment diagrams for the beam. (10) 4. See figure below. A triangular plate is suspended horizontally by three vertical cables. The weight of the plate is 240 N, and the center of gravity is located at the centroid of the triangle. Determine the tension forces in the three cables. (20) 5. (Bonus question, 10 points) The weight of the bucket is W = 1000 lb. The cable passes over pulleys at A and D. Neglect the friction between the cable and the pulleys, and neglect the weight of the truss members. Determine the axial force in member HG....
