A "truss" is a type of structure that is being used when building infrastructures (mainly the roof). In this type of structure, force is mainly applied to only two points. Thus, the term "two-force members" that constitutes the structure.

A "suspension" is a type of structure that is also being used particularly in making bridges (Suspension bridges). They can also be used in making large-span roofs in industrial buildings.

2. What are the benefits of using each type of construction?

The main benefit of using "truss" is that load is applied only on the two joints. This makes it physically stronger, easier to install and cost-effective. Suspension structure, on the other hand, allows the transmission of loads to the ground. This is made possible with the help of a number of cables.

3. What do these two types of construction have in common?

Both of the "truss" and "suspension" are cost-effective for they only need a few amount of supplies. Both of them carry loads by distributing them to other places. The weight of a roof in a "truss" is being distributed to the other walls while the weight of the roof in a "suspension" is being distributed to cable going down the ground.
