Learn the differences between the forces of tension and compression ... Their plan should clearly identify tension and compression members. Explain to students that for the purposes of this activity, the two crosspieces between the towers are non-load-bearing and can each be made of a single piece of soda straw.

Question (a): What is the difference between "Compression" and "Tensile Strength"? Comment: COMPRESSION: When you push on both sides of a spring or sleep on a spring bed, you are applying a force that is due to compression. On the other hand, if you pull on both sides of the spring you applying TENSION force.

The essential difference between compression or tension springs is that tension springs have initial tension coiled into them. This is the resistance to a pulling force as a result of the coils being wound tightly together.

The answer to this question by material and structure engineers is compression and tension. In other words, these structures are designed in a way that all forces including weight and wind will be converted to tensile and compressive forces on the structural material.
