Megajaya Sein. Bhd. is a consulting company specialized in analyzing and designing bridges in Alar Setar, Kedah. This company has been assigned to analyze and propose a bridge truss design to cross Sungai Kechi! in Yan, Kedah for Malayan Railways Limited. Figure 3 shows the cross-section of the Sungai Kechil. The required clear span for the proposed bridge truss is 6 m length from A to B. The bridge truss was subjected to a maximum load of 132 kN/m along the bridge truss span and a maximum length of the truss member is not more than 2.5 m. (a) Sketch a bridge truss that is internally and externally stable and the maximum length of the truss, the member is not more than 2.5 m? (b) Calculate the support reactions at A and B by assuming pinned support at A and roller support at B. (c) Determine the compression and tension force for each bridge truss member using Method of Joint. ( d) Check any THREE (3) bridge truss member using Method of Section for validation
