5. (a) A hydraulic piston is used to stretch the steel cables of a bridge. Figure 5a shows the cable attached to a member of the bridge at point A and the ground at point C. Determine the tension of each segment of the cable, AB and BC, if the force which the hydraulic piston DB exerts is 50 kN [Use Geometric Method Only without coordinates) [8 marks) B 50 KN 450 cm DA 400 cm 250 cm Figure 5a (b) The weight of a spherical tank acting vertically downwards induces a moment of magnitude M! = 4/13 kNm about point B (see Figure 5b). The tank is supported by a pole AO and steel cables AB and AC. If the force in the pole acts along its axis, O Determine the forces in AO, AB, and AC for equilibrium.
