what materials that can be used to make a suspension bridge
They help keep the cables suspended, and convert the heaviness from the cables into pressure that forces the towers into the ground. They can be made out of iron/steel just like the cables or sometimes stone. For example the Clifton Suspension Bridge towers are made out of Pennant Stone.It is originated from England, Bristol and Wales, and is hard and heavy. It has aesthetic properties as it can be smoothed down to look nice, and has nice colouring.hey undergo a lot of tension and compressive forces, and for this they need to be extremely strong. The material used in these cables is steel, it is an alloy of iron, manganese and tungsten, which make it extremely strong, durable and hard. Also tungsten gives it a rather high boiling point too.
