This professional tool called Clinometer is the most precise slope measurement tool for the iPhone, iPod Touch and iPad. Please use our support link if you have questions and suggestions, we don’t read the iTunes reviews every day. Well just like all the apps in this list, it will also let you measure the inclination and angle of any surface, whether it is floor, walls or any object you need to find the right position for.
To make sure that the measure is horizontal, you should use your clinometer app or spirit level so you can measure it correctly. Watch How to measure angles and slope using your android smartphone | Bubble Level video. In this the limited but therefore free version of Clinometer.
Finding The Height Of The Tree
Therefore, the tree must be shorter than the sum of the readings. Another way to think of it is that 80 feet is 80 percent of the calibration distance of 100 feet, so the tree has to be 80 percent of the sum of the slope readings. Likewise, if one were 150 feet from the tree, the total tree height would be 150 percent or 1.5 times, the sum of the slope readings. If you’re standing on a concave face it’s impossible to sight slope angles so you’ll have to estimate the steepness or take point measurements.
- Engineers must be able to calculate the sizes of extremely large or distant objects, including bridges and skyscrapers.
- A third person can be scouting ahead for obstacles or good locations.
- Place the sighting pole you made in step 12 on point Y of the slope you are measuring, about m away.
- Each number is the degrees off horizontal of the line beneath the number.
- To make it cheaper we hung a weight from a string at a 90 degree angle below it Download Clinometer APK for Android.
- Multiplying D by the tangent of a gives the height of the object above the observer, and by the tangent of b the depth of the object below the observer.
Some embodiments of the invention permit reliable operation in an environment with a high level of vibration. An accurate digital readout is accomplished with low power circuitry. The function of ganged switch 40 and 49 is to select the type of calibration or type of readout desired from three and one-half digit LCD readout unit 35. If ganged switch 40, 49 is in the position shown, the readout is calibrated to indicate the number of degrees of inclination of clinometer 1 from 90 degrees to +90 degrees. If ganged switch 40, 49 is in the position shown, the voltage +1.800 volts will be produced on conductor 67, and -1.800 volts will be produced on conductor 68.
Angle Of Elevation Activity
This guided worksheet is the perfect lesson for students to experience trigonometry around their schools! Students can use the compass app on their iphones to measure the angles of elevation to calculate heights of different objects around campus. An inclinometer is the device used for pointing and measuring the angles of the earth’s surface. In the marine industry, inclinometers are used mainly on ships and oil rigs to measure how much a vessel slants while being on still water and when the water is choppy. The inclinometer is also known as a clinometer. An apparatus for measuring a vertical angle, a slope, or the height of a large object (e.g. a tree).
