A simply supported bridge is to be constructed in a Patna city and two designs have been proposed as shown in Case A and Case B. The truss members are to be made from steel. The deck consists of 1.5-m-long timber planks that have a mass of 20 kg/m². The Indian design code states the live load on the deck is required to be (5+0.25y) kPa. Consider the deck to be simply supported on stringers. Floor beams then transmit the load to the bottom joints of the truss. In each case find the member subjected to the largest tension and largest compression load and suggest why you would choose one design over the other. Neglect the weights of the truss members. Letter 'y'in the figure is your Group number. Show all the steps clearly.
