The assembly in Figure Q3 consists of two steel suspender rods AC and BD attached to a weightless uniform rigid beam AB. Each rod has a diameter of 12 mm. The modulus of elasticity of the rods, E, is 200 kN/mm. (a) Determine the position x for the 1500 N loading so that the beam remains in a horizontal position after the load is applied. (12 marks) (b) Determine the normal stress in both rods AC and BD. (c) (4 marks) Determine the shear stress in both pins A and B if both connections are in double shear condition. The diameter for both pins is 6 mm. D 500 mm 1500 N 300 mm x 600 mm FIGURE Q3 B (4 marks) (20 marks)
