Guide

1

easiest to assume the slope using inclinometer, if you do not, try to make this simple device yourself.Take the rail and attach it to the frame in a corner of the rack, position the axis of the pendulum.The pendulum is made of two rings, plates, and sinker pointer.When measuring bob will move between the rails with notches.Inside, there are graduated scale, making it with a protractor.

2

To measure the slope of the roof rail attach at a right angle to the ridge and look at what the division of the scale pointer stopped.You will receive the value of the slope in degrees.

3

To measure the slope with the help of available resources without
creating special device, mentally construct a right triangle, the inclined side of which will coincide with the inclined surface of one leg is parallel to the ground, and the second - is perpendicular.Now, your task - to find at least two sides of the triangle.

4

on land or roads can take advantage disappears.Determine with the help of the height of the point above sea level, and see the difference and the distance between points pomerte tape.If leveling is not, just take a long board and place it horizontally (align the level gauge or the national way).At the bottom of this sheet under the plank bricks or other available means.Measure the length and height of the board of bricks.

5

If the object is far away, take a picture of it and pomerte length sides of the triangle in the picture.Find the length of the two legs - both horizontal and vertical.

6

Now divide the length of the opposite (vertical) leg on the length of the adjacent (horizontal).To get the slope in percentage, multiply by 100%, and if you multiply by dividing the 1000 ‰, then learn bias ppm.

7

To find the value of the slope in degrees, get a scientific calculator.It may be an ordinary electronic device with advanced or program "Calculator" on your computer (you can find on the internet and online).Enter obtained by dividing the number of the legs, and then click the arctangent (atan or atg).You will receive a surface slope in degrees.
