Solution

Suspension bridge

In order to understand the logic why it does not fail structurally, we need to understand the concept that lies in the mechanism of the suspension bridge. Firstly it is a special type of bridge as compared to other bridges.In this bridge loads of bridges are carried by suspenders between towers and anchored both at the ends of the bridge.It is to be noted that anchorage of the bridge must strong enough handle the load of the bridge deck suspended by suspenders.Contributes greater redundancy. It is the design as well as the material put use that makes it safe and doesn\'t let the suspension bridge fail.

Electrical transmission towers:

The design of Electrical transmission towers uses lattice members and are designed in such a way that it withholds the loads subjected from the electrical wires as well as the wind, ice so in order to understand that why they don\'t fail structurally because they resist all the loads from the withstanding structure and carry the loads respectively like the suspension bridge. One can even say that anchorage prevents the both structure to resist failure and the type of material put to use.The truss design also helps boost the strengthen the electrical transmission towers.These structures have square bases that have four points contact to ground.It is also designed in such way that it transfers the mechanical load to the adjacent structure.So we observe that our structure doesn\'t fail structurally.
