Measuring Techniques with Calipers

The video tutorial covers the importance of measurement in construction and design, focusing on the use of calipers. It explains different types of measurement tools, their accuracy, and how to use calipers for precise measurements. The tutorial also includes a practical exercise where students design a box top using calipers, emphasizing the importance of precision in engineering and design tasks.
