Why concrete is strong in compression and weak in tension?
Concrete is strong in compression, as the aggregate efficiently carries the compression load. However, it is weak in tension as the cement holding the aggregate in place can crack, allowing the structure to fail. Reinforced concrete solves these problems by adding metal reinforcing bars, glass fiber, or plastic fiber to carry tensile loads

What Causes the earth to fold and crack?
The Earth's crust can fold and crack due to tectonic forces, such as compression and tension along plate boundaries. Compression causes rocks to fold, creating mountain ranges, while tension leads to the formation of faults and fractures, resulting in earthquakes. Other factors such as volcanic activity, erosion, and gravitational forces can also contribute to the folding and cracking of the Earth's crust.
Does Tension stress creates folded mountains compression stress creates fault-block mountains and the third type of mountain is volcanic?
First understand that in GEOLOGY there can be no such thing as a "tension stress". Gravity ensures that all things are in compression. The only change is in the direction of maximum stress. When gravity (downwards) is the direction of maximum stress and one or other of the horizontal stresses decays slightly, fault block mountains form. When gravity (downwards) becomes the lowest stress, reverse faults (thrusts) and fold mountains are formed. When a hydraulic fluid (magma) penetrates a rheologically solid medium this will crack the medium an rise towards the surface. If the magma contains gas this will fizz and cause a volcano.- Is the Answer True or False?-Olivia
What results when forces within the earth are pulled or stretched from opposite?
Tension
How tension crack causes slope failure?
Thension crack is generated by the difference in shear movement along the failure surface or slip plane. It formed in the upper slope face before the major failure surface appeared. So, the total shear resistance and thus the safety factor will reduce after this tension crack developement. However, this tension crack will stop developing when it reaches a critical depth. And, a new tension crack will develope behind that previous crack.

What effect can a seed have on rock?
A seed that falls into a crack in a rock can help to expand or even split the rock. The resulting plant can gradually expand within the crack and attract moisture that will stress the rock with freeze and thaw cycles.
Would a blown head gasket cause loss of compression?
It is possible but it depends on where the crack is. If the crack is from the combustion chamber out, such as through a coolant passage it can also suck in coolant/antifreeze and loose compression.
How does a crack occur?
A crack can occur when there is stress on a material that exceeds its strength, causing it to fracture. This stress can be caused by factors such as impacts, pressure, temperature changes, or structural weaknesses in the material. Once a crack forms, it can propagate and grow over time if the stress is not relieved.
What is the depth of tension crack in retaining wall?
h=2c
What effect do you get when a engine cylinder head has been skimmed to its last?
You will get a lumpy idle due to very high compression. also you might blow your head gasket out or crack a piston or connecting rod.
