A2. In a beam supported at both its ends the lower half of the beam will be under tension, and the upper half of the beam will be under compression.

What is compression zone and tension zone?

In snow avalanches, when friction or other mechanical stops are not enough to hold it in place, and the angle is prime, it is held in place by tension and compression. The tension zones, are convex parts near the top and sides of the slide path; and compression zones, are the concave parts near the bottom and sides of the path. Snow is weak in tension and stronger in compression. If the load of snow on the slope has a lubricating layer, underneath it, and a good running surface, at sliding angle (38 degrees is prime), then the only thing hold the snow from sliding is the tension at the top, and the compression at the bottom. Upset this balance by either skiing through (cutting) one zone or the other, or use explosive in one of the zones, and you will have created a slab avalanche. In avalanche control they are often referred to as the "sweet spot"


What occurs when materials of the Earth's crust are stretch causing them to thin?

tension


Does higher tension evaporat water faster then low tension?

Tension does not have anything to do with evaporation.


What boundary is between the zone of aeration and zone of saturation?

The zone of aeration is where there is both air and water within the pore spaces in the ground. In the zone of saturation the pore spaces are totally filled with water. The boundary between these two zones is known as the water table or phreatic surface.

What do you call when plates push together?

It is called tectonic movement. It leads to accumulation of tension. Excessive tension leads to earthquake. ***** It is known as a convergent boundary. If one edge becomes forced downwards into the mantle it becomes a subduction zone.

What is the difference of singly reinforced beam from doubly reinforced beam?

Singly reinforced beams have reinforcing only on the tension face. Doubly reinforced beams have reinforcing on the tension and compression face. Doubly reinforced beams can increase section capacity, but are primarily used to increase the ductility of the concrete beam. In certain codes, if the concrete section is controlled by the concrete failing in compression before the tension steel rebar yields (called a compression-controlled or brittle section), the calculated section capacity must be reduced to account for the brittle and sudden/unpredictable nature of a compression controlled (also called a brittle) failure. In order to make the section controlled by the yielding of the tension reinforcement (called a tension-controlled or ductile section), the ductility must be increased. This can be accomplished by adding steel in the compression zone, which gives strength to the compression area, thereby delaying the failure of the concrete. Enough compression steel can cause the section to switch from a brittle mode-of-failure to a ductile mode-of-failure, thereby permitting the designer to not decrease the section capacity from its calculated value. When identifying a doubly- reinforced beam, be sure that the steel in the compression area is meant to be for strength. Oftentimes, all faces of a beam will have some reinforcing for temperature/shrinkage protection and to tie the stirrups to. Steel that is only there for temp/shrinkage or to facilitate tying the rebar will usually be small and not much of it. In buildings, they will be often #3 bars @ 12" centers. In bridges, they may be #4 bars. These small bars should not be counted as compression-zone reinforcing. Look for bars in the compression zone that are of similar size to the main tension reinforcing.


What is the need of conservation?

The need for conversation is to just ease the tension. Ever heard of akward silence? It feels akward right? Talking just puts people more in a comfort zone.
