Which of the following is a common scale used on technical drawings?

In technical drawings, scales are essential for accurately representing the dimensions of objects. A common scale is one that is widely used and easily understood in the field. The correct choice involves a scale of 1/4 inch and 1:100, which corresponds to a ratio where one unit on the drawing represents 100 of the same units in reality.

This particular scale is frequently utilized in architectural and engineering drawings because it allows for a clear and understandable representation of larger objects or spaces, making it practical for clients, contractors, and engineers to visualize the dimensions accurately on relatively smaller paper sizes. The 1/4 inch scale is a standard format in various disciplines, providing a balance between detail and ease of understanding.

Other options either reference non-standard scales for technical drawings or scales that are less common, making them less suitable for typical applications in the industry. In contrast, using 1/4 inch to 1 foot (1:100) is a familiar and effective scaling method in technical documentation, which is why it stands out as the correct choice.
