Measuring the Height of a Tall Object Using a Clinometer

The video tutorial demonstrates how to measure the height of a tall object using a clinometer. It explains the process of positioning oneself at a distance, measuring the angle of elevation, and using trigonometric formulas to calculate the height. The tutorial provides a step-by-step guide, including the final calculation of the object's total height, and concludes with additional resources for further learning.

What is the first step in measuring the height of a tall object using a clinometer?

• Measure the height of the object directly.

• Place yourself at a distance from the object.

• Calculate the angle of elevation.

• Record the reading on the clinometer.

What should you do after placing yourself at a distance from the tall object?

• Measure the distance from the base of the object to your standing point.

• Calculate the height of the object.

• Record the angle of elevation.

• Move closer to the object.

How do you use the clinometer to measure the angle of elevation?

• Calculate the height of the object.

• Measure the distance from the object.

• Place the clinometer on the ground.

• Hold the clinometer and look through the straw to locate the end of the object.

What is the angle of elevation recorded in the example?

• 30 degrees

• 90 degrees

• 45 degrees

• 60 degrees

What formula is used to calculate the height of the object above eye level?

• sin x = l / h

• cos x = l / h

• tan x = l / h

• cot x = l / h

What is the value of tan 45 degrees?

• 0.5

• 2

• 1

• 0

What is the calculated height of the flagpole above eye level?

• 3 meters

• 4 meters

• 6 meters

• 5 meters

What additional measurement is needed to determine the total height of the object?

• The width of the object.

• The angle of elevation.

• The height of the observer's eyes from the ground.

• The distance from the object to the observer.

What is the height of the observer's eyes from the ground in the example?

• 1.65 meters

• 1.5 meters

• 1.85 meters

• 1.75 meters

What is the total height of the flagpole calculated in the example?

• 5 meters

• 6 meters

• 6.65 meters

• 7 meters
