Calculator "How to calculate the angle of the roof" - instruction
Calculator for calculating the angle of the roof slope is extremely simple, it will require only two linear values. Consider first a schematic illustration of the roof, so it becomes clearer that we will count. At its core, any roof can be divided into triangles, the simplest option for counting is a gable roof, the illustration of which is shown in the figure.
We see an isosceles triangle, the formula for calculating the angle of which is based exclusively on the geometry of geometry for the school course. The simplicity of the gable roof is that its height is lowered to the base at a right angle, which makes it possible to calculate the angle at the base by simple formulas of cosines or sines.
But for this you need to know any two parameters, either a cathet and a hypotenuse, or two legs.
Let's consider how to calculate the angle of the roof using our calculator:
- we have the legs of the ridge( H) and half the width of the base( W), and the hypotenuse is the length of the rafters( L);
- in the calculator you need to enter only two parameters to choose from, which is easier for you to measure( creeping, for example, with a tape measure), or maybe you already know the values from the house project;
- to fill the fields with numbers, check the two options, only then the field for data entry will become active;
- after entering numbers under the list of parameters appears a line with the inscription "Angle", where the required value will be written;
- additional bonus program will automatically calculate the third parameter, if you for some reason do not know it.
Thus, in a few seconds the problem is solved, how to calculate the slope of the roof. This certainly saves you time, because you do not have to painfully recall the school course of geometry, which is sometimes very difficult to do, even if you were studying for a single five.
How to calculate the angle of the roof - other ways of calculating the
You can calculate the angle of the roof without a calculator, although, of course, there will be more trouble. There is such a tool - inclinometer. The device is uncomplicated: several racks with divisions and a pendulum. The main staff is placed at right angles to the ridge, and the pointer of the pendulum will show the value on the scale of divisions. Here, in fact, the whole secret, only for this it is necessary to go out into the street and twist this thing in hands, or the calculator.
There is one more problem when calculating the angle of the roof slope when it is not symmetrical. Then you can not use the width of the base in the calculations, it is better to take only the height of the ridge( H) and the length of the rafters( L).And if the roof is not gable, then there are more such independent triangles, although another formula can be used to calculate the angles of the pyramid( for a four-slope).
