What is the difference between one way and two way slab?
Answer:
Wire Mesh Weight Calculation Formula
All weight are in units of kilograms
Indian Quality Standard
brick =1600kg/m3
if LY/LX>2 than we use one way slab if <2 than use two way slab.One way slab supported only two direction and two way slab supported in all four direction.

Right Triangle
Sine, Cosine and Tangent are all based on a Right-Angled Triangle
Before getting stuck into the functions, it helps to give a name to each side of a right triangle:
"Hypotenuse" is the long one
Sine, Cosine and Tangent
To calculate them:
Sine Function:
Cosine Function:
Tangent Function:
In picture form:
"Opposite" is opposite to the angle θ"Adjacent" is adjacent (next to) to the angle θ
Adjacent is always next to the angle
And Opposite is opposite the angle
Sine, Cosine and Tangent are the three main functions in trigonometry.
They are often shortened to sin, cos and tan.
Divide the length of one side by another side
... but you must know which sides!
For a triangle with an angle θ, the functions are calculated this way:
