In compressive load cell weight is applied on load cell and it gets compressed. Due to this compression we can measure the applied load. You can check out at http://www.adiartech.com/compression90210.html
and in tension load cell see this link that i came across

All cells have internal resistance. The value is very small when the cell is fresh. The value increases slightly and slowly as the cell discharges. So the potential difference across the cell will not noticeably change when a load is initially connected. As the cell becomes more discharged, the drop in potential difference upon connecting a load will increase. The point at which the cell is no longer any use depends on the minimum voltage which the load requires, and the current required by it.
The stress reduction factor is a product of the relationship between the Unconfined compressive strength of a rock and the sigma 1, or principal stress field in that area. The higher the value, the more likely the rock is to deform when placed under load.
Electric Source You hook both to an electric Load.
5000-5800 (35-40 MPa)
The load conductor is connected to the load side of the generator breaker. Once the generator is up to speed the load breaker is closed and the voltage is then applied to the load.
singly reinforcement beam have steel provided only one side tension an another side compression. tension takes steel load or tensile load and compression takes concrete or compressive load.
If the load is from the top pointing down, compessive stress is at the top and tension at the bottom
Load divided by area of load applied (Load per unit area)
It's a strut.
The compressive strength of bricks varies depending on the type of bricks and what they are used for. The compressive strength of conventional red bricks is 40 to 65 Kg/cm2. In comparison, flyash bricks have a compressive strength of 70 to 120 Kg/cm2.
Compressive strength is greater than tensile strength not just in beams, but in metals, concrete, ceramics, ice, and many other materials. Consider a uniaxial test of tension or compression. Because the cross-sectional area of the sample increases with the load, the stress is actually lower than what we would expect from dividing the load by the area of an unloaded sample. The opposite is true for a tension test. The cross section gets smaller with increasing load. Remember this is true regardless of whether the deformations are reversible and elastic or irreversible and plastic. Therefore the nominal compressive strength is greater than the nominal tensile strength even in a perfectly isotropic material.
beam load formula
To calculate the compressive strength of a 150mm x 150mm x 150mm cube, first cure the concrete cube for the specified period (usually 28 days). Then, use a compression testing machine to apply a load until the cube fails, recording the maximum load at failure. The compressive strength is calculated by dividing the maximum load (in Newtons) by the cross-sectional area of the cube (in square millimeters), using the formula: Compressive Strength (MPa) = Load (N) / Area (mm²).

the load is compression and tension
tension force is the force that is opposite to compressive force.
as we know concrete has very high strength and it is very good in taking compressive loads,and slabs are mostly subjected to the compressive load or uniformly distributed loads.
