How can a clinometer be used to measure slope?

How can a clinometer be used to measure slope?

Slope generally is measured with an instrument called a clinometer. When sighting through a clinometer, the measuring line is placed on the target, and %slope is read from the scale. Both eyes are open, as one eye reads the scale, and the other eye sights on the target (Figure 1.7).

What is clinometer used for?

A clinometer is a simple device used to measure angles. It can be used to measure the slope of a specific terrain, the height of a building or tree, or the declination of a celestial body.

Which instrument is used to measure the slope?

clinometers
A clinometer is an instrument for measuring slopes or vertical angles. There are various types of clinometers, but they all include a graduated arc similar to a protractor (see Section 3.3, step 11). To use the clinometer, you hold it in your hand and read the slope against this arc.

Is there an app to measure slope?

This professional tool called Clinometer is the most precise (all you can get with some calculations) slope measurement tool for the iPhone, iPod Touch and iPad using all sides of the device plus the camera.

What angle does a clinometer measure?

elevation angles
By definition, a clinometer is an optical device for measuring elevation angles above horizontal (angles of elevation). A metal tube allows the user to sight the top of an object and a protractor-like device on the side measures out the elevation angle.

What is a slope inclinometer?

Slope inclinometers are geotechnical instruments used to measure horizontal displacements along various points on a borehole. For this reason, sometimes they are also called borehole inclinometers or simply inclinometers.

How do I measure a slope?

To calculate percent slope, divide the difference between the elevations of two points by the distance between them, then multiply the quotient by 100. The difference in elevation between points is called the rise. The distance between the points is called the run. Thus, percent slope equals (rise / run) x 100.

Who uses a clinometer?

Geologists and Surveyors Use of the clinometer with a specific mathematical formula–height x distance x angle–assists geologists to assess the height of a tree or a mountain. Surveyors, on the other hand, use this multipurpose instrument for measuring angles in reference to gravity.

How is a clinometer used to measure the height of an object?

A clinometer is a fairly simple instrument which is used to measure the angle of a slope. By using the principles of trigonometry, the height of tall objects can be calculated from the angles measured. A clinometer can easily be made from a large protractor.

How do you find the slope in construction?

Convert the rise and run to the same units and then divide the rise by the run. Multiply this number by 100 and you have the percentage slope. For instance, 3″ rise divided by 36″ run = . 083 x 100 = an 8.3% slope.

How do you use a clinometer at home?

Tilt the clinometer until you can look through the straw or paper tube and see the top of a tall object you want to measure, such as a building. You can use this method to measure the angle between you and the top of that object, or the object’s height. Measure the angle using the protractor.
