Drawing a tangent and normal to the involute of a circle is an essential technique in technical drawing, particularly for gear design and mechanical engineering. The tangent represents the direction of the curve at a specific point, while the normal is perpendicular to the tangent, often indicating the line of force. This guide explains how to accurately construct both the tangent and normal to the involute of a circle.
By carefully following these steps, you’ve successfully constructed both the tangent and normal to the involute of a circle. These techniques are vital in engineering design, especially in gear systems where the involute profile ensures efficient transmission of motion and force.
