Tangency Problem 4: How to Construct the Figure Accurately – Drawing the Figure Step by Step

Описание: Welcome back to Engineering Drawing Made Easy!
In this tutorial, we work through Tangency Problem 4, focusing on how to construct arcs of radii 7 mm, 32 mm, and 26 mm using the rules of internal and external tangency.

This problem looks simple at first glance, but it requires a clear understanding of how arcs relate on a common center line. In this video, you will learn how to:

• Read and interpret the given dimensions correctly
• Identify which arcs touch internally and which ones touch externally
• Apply tangency rules using addition and subtraction of radii
• Use a center line to position arcs accurately
• Locate arc centers step by step using your compass and ruler
• Complete the figure neatly and check for accuracy

This tutorial is perfect for students learning engineering drawing at the tertiary level and anyone who wants to strengthen their understanding of tangency constructions.

Pause the video and draw along — it makes the learning process easier and more effective.
