FAQs on 01 - How to measure height of a tall object using Clinometer - Class 10 - Maths Video Lecture
| 1. How does a clinometer measure the height of a tall object? |  |
Ans. A clinometer is a device used to measure angles of inclination or elevation. To measure the height of a tall object using a clinometer, we need to follow these steps:
1. Stand at a known distance away from the base of the object.
2. Look through the clinometer's sight and align it with the base of the object.
3. Use the clinometer's scale to measure the angle of elevation from the base of the object to the top.
4. Measure the distance from your eye level to the ground.
5. Use trigonometry (specifically, the tangent function) to calculate the height of the tall object by using the angle of elevation and the distance from your eye level to the ground.
| 2. What is the purpose of using a clinometer to measure the height of a tall object? | |
Ans. The purpose of using a clinometer to measure the height of a tall object is to obtain an accurate and convenient method of measurement. By utilizing trigonometry principles, a clinometer allows us to calculate the height without physically climbing the object or using complex equipment. It provides a practical and efficient way to measure heights, particularly in situations where direct measurements are challenging or dangerous.
| 3. Can a clinometer measure the height of any tall object? | |
Ans. Yes, a clinometer can be used to measure the height of any tall object as long as it is within the device's range and the user can obtain a clear line of sight from the base to the top of the object. However, it is important to note that the accuracy of the measurement depends on several factors, such as the precision of the clinometer, the user's ability to align the device correctly, and any obstacles that might obstruct the line of sight.
| 4. What are the limitations of using a clinometer to measure the height of a tall object? | |
Ans. While a clinometer can be a useful tool for measuring the height of a tall object, it does have some limitations. These include:
- Accuracy: The precision of the measurement depends on the accuracy of the clinometer and the user's ability to align it correctly.
- Line of sight: If there are obstacles, such as trees or buildings, obstructing the line of sight from the base to the top of the object, it may be difficult or impossible to measure the height accurately.
- Distance: The clinometer's range may limit the maximum distance from which the height can be measured. If the object is too far away, the clinometer may not provide accurate results.
- Sloping ground: If the ground beneath the object is not level, it can introduce errors in the measurement. In such cases, additional calculations or adjustments may be necessary.
| 5. Are there any alternative methods to measure the height of a tall object? | |
Ans. Yes, there are alternative methods to measure the height of a tall object. Some common methods include:
- Using a theodolite: A theodolite is a more precise and sophisticated instrument that measures both horizontal and vertical angles. It can provide more accurate height measurements compared to a clinometer.
- Laser rangefinders: Laser rangefinders use lasers to measure the distance between the observer and the object. By combining this distance with the angle of elevation, the height of the object can be calculated.
- Taping or chaining: In this method, a tape measure or chain is used to directly measure the height of the object. This method is suitable for objects that are easily accessible and not too tall.
- Photogrammetry: By taking photographs of the object from different angles and using specialized software, the height can be estimated through the process of photogrammetry. This method is commonly used in fields such as surveying and architecture.

so now I demonstrate to you how to
measure the height of the tall object
using a chronometer so first you place
yourself at a distance away from the
tall of chick then measure the distance
from the base of the object to the point
where you're standing here I'm going to
measure the height of the flagpole so
first you take the Queen o meter in your
hand and locate the end of the hot chick
once you've located the end of the
object through the straw let the kilo
meters be steady once it becomes steady
record the reading on the clinometer
where the string touches the scale on
the clinometer so here i've got an angle
of elevation of 45 degrees now that we
have recorded the angle of elevation of
the flagpole let us calculate the height
of the blackboard now to calculate the
height of the and die of flagpole we
first need to calculate the height of
the flagpole above our eye level so now
since I have placed myself five meters
away from the foot of the blackboard if
we consider this distance to be small L
then L equals to five meters
now to calculate the height of the
object that is the flagpole above our
eye level we'll use the formula tan x
equals to L upon H where L is the
distance between yourself and the
flagpole and small H is the height of
the flagpole by taking H on the LHS and
daleks on our HS we get it equals to L
upon tallix we already know that L
equals to 5 meters and 10 or 45 is
nothing but 1 therefore by substituting
these values in the equation we get H
equals to 5 meters upon 1 which is
nothing but 5 meters now next we move on
to the entire height of the object the
height H of the object is now given by H
equals to L upon tan X plus D we have
already calculated the value of L upon
taric's and since D is nothing but the
height of your eyes from the ground by
substituting the values in this equation
we get H equals to 5 plus one point 6 5
which equals to 6 point 6 5 meters thus
the height of the blackboard is six
point six five meters
I hope you all understood this activity
