The truss shown below is supported by a pin at A and a rocker at G. Each of the six horizontal members at the bottom of the truss are 2 m in length. (1) Identify any zero force members by inspecting the joints and list them. (ii) Determine the support reactions at pin A and rocker G. (ili) Determine the forces in members KJ, CJ and CD. Indicate if each of these is in tension or compression by writing (T) or (C), respectively, next to their values. Note: Free body diagram(s) must be drawn for full credit. 6 kN 3 kN 12 kN 9 kN 6 kN – H 3 m A .

P = CAN VOO Beam AB is supported by a pin at A and a roller at B. The loading distribution is shown. The shapes of the shear force and bending moment diagrams are also given. However, not all numerical values are provided. Find the missing values as asked for in questions (a) to (e). Note: The answers are all numerical values. (a) Determine the magnitude of the vertical component of the reaction at A. MN.m Ay = A2m1m11 1 m (b) Determine the magnitude of the reaction force at B. By = V (kN) (c) Determine the intensity of the uniform distributed load w. xm (d) Determine the magnitude of force F. FE (e) Determine the magnitude of the couple moment M. ME M.(N.m) * (m) Refer to the figure below. A is a fixed support and B is a pin. Determine the reactions at supports A and B. Appropriate free body diagram(s) must be drawn. Indicate directions using arrows next to your final answer. 750 lb/ft 400 lb/ft 6 ft- 6 ft- 8 ft. Support reaction(s) at A Support reaction(s) at B Beam ABC consists of two segments connected by a hinge at B. There is a fixed support at A and a roller support at C. The support reactions have already been calculated for you. Draw neat and well-labelled shear and bending moment diagrams. For full credit you need to clearly indicate on the diagram: • Degree of each polynomial. • Location of the points with zero shear if any • Values of peak moments within a section • All units and axes labels with neatly drawn curves and lines. Report the magnitudes of maximum shear force and bending moment in boxes (absolute value: either positive or negative). 6 ibited 20 lb bitt 30 lb.ft 206.76 Ib.ft A 10 ft 46.46 lb 1 ft, 1 ft1 ft 31.54 lb Maximum V (+ or -) Maximum M (+ or -) 20 lb 30 lb.ft 206.76 Ib.ft A4 10 ft 46.46 lb 31.54 lb
