The suspension bridge is a type of bridge found all over the world. The major parts are under pressure from compressive and tensile forces. The vertical beams, or pylons, are in compression, due to the enormous weight of the cables and deck and are fixed into the ground for stability. The main cables are in tension, due to the ‘stretching’ forces applied to them. They stretch from bank to bank and hold the pylons in position, stopping them moving/swaying too much. Also, the main cables secure the suspension cables and deck (which runs from one side to the other), an immense weight. The suspension cables are in tension, holding up the part of the bridge between the pylons, and are stretched by the weight of the deck.
