For what purpose are pins and clips used in engineering drawings?
To fasten the drawing sheet on to the drawing board firmly so that it does not shake
The correct answer is Option 1: To fasten the drawing sheet onto the drawing board firmly so that it does not shake.
Pins and clips in engineering drawing serve the primary purpose of securely holding the drawing sheet to the drawing board. This prevents the paper from moving or shifting during the drawing process, ensuring accuracy and precision. Options 2, 3, and 4 describe the functions of other drawing instruments, not pins and clips.
While pins provide a strong, point-based hold, clips offer a broader clamping mechanism, both achieving the same fundamental goal of securing the drawing sheet. The stability they provide is crucial for creating accurate and detailed technical drawings.
