Measuring the Angled and Circular Wall Part 1

Summary

In this instructional video, Donald Cooper outlines essential techniques for field measuring angled walls in kitchen design. He emphasizes the importance of being well-equipped with tools like rulers, tape measures, and trigonometric tables. The lesson covers measuring both acute and obtuse angled walls, detailing methods for handling obstacles and ensuring accurate dimensions. Through clear explanations of geometric principles and practical tips, Cooper guides viewers step-by-step in calculating angles and radii, equipping them with the skills to perform effective field measurements in real-world scenarios.

Takeaways

• 📏 Ensure you have all necessary tools for a field measure, including a ruler, templates, and tape measures.
• 📝 Create a clear sketch of the room's dimensions using double lines to represent walls.
• 📐 Understand the basic properties of triangles to measure angles effectively.
• 🔍 Avoid using easy-read tape measures, as they may not provide confidence in measurements.
• 📊 Use trigonometric formulas (sine, cosine, tangent) to determine angles and radii.
• ⚖️ Maintain focus during field measurements to avoid missing important elements.
• 🔄 Convert room dimensions into an imaginary triangle for better accuracy.
• 🔔 The radius of acute angled walls is essential for accurate measurements, typically under 90 degrees.
• 🗺️ Document the radius of obtuse angled walls correctly, avoiding assumptions.
• 📋 Save complex math and design planning for later; focus on accurate measurements during the field visit.

Q & A

What is the purpose of this lesson on field measuring?

The lesson aims to teach how to accurately measure angled walls in a room using specific tools and mathematical formulas.

What tools are recommended for a field measuring kit?

The kit should include a ruler or templates, camera, clipart, mechanical pencils, a notepad, painter's tape, flashlight, two carpenters' 90-degree angles, a checklist or construction details form, a level, and two tape measures.

Why should you avoid using an easy-read tape measure?

Easy-read tape measures can lead to a lack of confidence in measurements and may not always be available, making traditional tape measures a better choice.

What types of wall angles are covered in this lesson?

The lesson covers acute angles (under 90 degrees) and obtuse angles (over 90 degrees).

How do you begin measuring a room?

Start by drawing the shape of the room, measuring visible dimensions, and ensuring that the lines are drawn with a ruler and are legible.

What are the names of the sides in the imaginary triangle used for measurements?

The sides of the triangle are called the hypotenuse, adjacent, and opposite.

What formulas are used to determine the radius of an angle?

The formulas used are: sin (opposite/hypotenuse), cosine (adjacent/hypotenuse), and tangent (opposite/adjacent).

What should you do after calculating the radius?

Compare your results to the angles on the table of trigonometry to determine the actual angle measurement.

What is the common assumption for the radius of an obtuse angled wall?

It is often assumed to be 135 degrees unless documented otherwise on a blueprint.

Why is it important to stay focused during a field measure?

Staying focused is crucial to avoid missing important elements, especially when clients are present in the showroom.
