Tension and Compression
There are different forces on a materials such as Compression and Tension. Compression is pushing a material together. Tension is pulling a material apart. Concrete has good strength in Compression, but is weak in Tension. The steel reinforcement improves the resistance to tension of the concrete.
If you load it normal to the beam axis you get bending stresses ( tension and compression) and shear stresses. If you load it along the axis you get axial stress ( tension or compression)
The materials used to build skyscrapers are strong materials that can withstand a great tension and compression. Early days the skyscrapers are usually made by iron frame but now it uses lighter and stronger metal, steels.
This will cause the beam to bend. You need to see the beam like a stack of spaghetti. Extended spagghettis are in tension Shortened spaghettis are in compression (equals signs represent the beam, dots represent air) If it bends like this, it is tension on top, compression below ........=============....... ..===............................===.. =.........................................= If it bends like this, it is compression on top, tension bottom =.........................................= ..===............................===.. ........=============........
Flexural compression refers to the type of stress that occurs in a beam or structural member when it is subjected to a bending load. This compression stress acts on the upper portion of the beam, while tension occurs on the lower portion. It is important to consider both compression and tension when designing structural elements to ensure they can withstand bending loads.
In structural engineering, tension and compression are two types of forces that act on materials. Tension is a pulling force that stretches or elongates a material, while compression is a pushing force that shortens or compresses a material. The main difference between tension and compression is the direction in which the force is applied: tension pulls the material apart, while compression pushes the material together. These forces can affect the stability and strength of structures, so engineers must consider them carefully when designing buildings and bridges.
tension streches it compression squeezes it
Tension forces pull materials apart, while compression forces push them together. Tension can cause stretching and weakening, while compression can cause crushing and buckling. Both forces can affect the structural integrity of a material by causing deformation or failure if the material cannot withstand the applied forces.
Stone slabs are stronger under compression than tension. This is because most stone materials are able to withstand higher forces when being compressed rather than being pulled apart. Stress is distributed more evenly and effectively in compression, making stone slabs less likely to fail compared to tension.
Shapes like triangles are strong in tension and compression due to their ability to distribute forces evenly across their three sides, preventing deformation. Arches and domes are also effective in compression, as their curved structure efficiently transfers loads downward. In contrast, long and slender shapes, like beams, are typically stronger in tension than compression, as they can withstand stretching forces better than buckling under compressive loads. Overall, the geometric configuration plays a crucial role in determining a shape's strength in tension or compression.
A crack is caused by tension not compression because tension pulls matter apart while compression pushes matter together
Compression is the condition that occurs when a force squeezes an object, which is the opposite of tension. In compression, the object experiences a pushing or squeezing force that tends to compact its particles together. This can lead to deformation or structural failure if the object's material cannot withstand the compressive forces.

Tension and compression are not forces themselves, but rather types of forces that act on objects. Tension is a force that pulls or stretches an object, while compression is a force that pushes or squeezes an object. Both tension and compression are common forces in structural mechanics.
