What is the importance of tensile strength? - wikipedia ceramic roofing
The Wikipedia says: "tensile strength and modulus of elasticity and corrosion resistance is an important parameter used for the technical material in the structures and mechanical devices. It is found in materials and alloys, composites, ceramics, plastics and wood." So, how is the wood used, for example, in real life as it strained? The houses are not compressed wood instead of right?
sorry if I did anything wrong, I'm not familiar with this subject students (high school).

Traction accurate in the transition from a material resistant to plastic deformation. Once the material is plastically deformed, can recover its original shape.
This can occur, however, on the train or pressure. If you take a class for static structures, you will see that the basic structures such as trusses of the bridge with elements that are under tension and compression.
As for the wood firmly in real life, looking to establish yourself a breeze. Burden on the crossbar of the swing under stress, although not immediately apparent. The changes create a moment in the beam that produces a tensile stress.
Good question ...
For many materials, the train (train) and compressive strength are similar. Ultimate or train-maximum is easy to see in a lab and you can tell how much stress a material can withstand. To overcome this stress, is dangerous because the device fails, and nobody wants that. The mechanisms are complex, however. How long does a fracture also depends on applied, as long as the tension on the material and if the material is already preloaded. This still depends on the orientation of the molecules in the material.
Because the materials have different molecular structures, the level of porosity, etc. Examination of the tensile strength is a good way to see how a solid material is subject to certain conditionsIons.
Wood, in particular, is called composite. It consists of organic fibers in a matrix of lignin exposed. A unique feature of composite materials is that they behave differently in different directions. How can a piece of wood that was cut at an angle that can actually both experience compression and tension, but in different directions. But in general, while the compressive strength can be tested, tensile strength is a general idea of how a material will behave under stress and pressure, provided a compressive stress of similar magnitude.
