The base of the flange shown in the drawing is actually 16 in . Its drawing width is 5 in .
(a) What will be the actual dimension A if A is 3.75 in . on the drawing?
(b) Find the scale factor of the drawing.

To find the actual dimension A, you can use the ratio of the actual base to the drawing width. If the drawing width is 5 inches and the actual base is 16 inches, you calculate the scale factor first: Scale factor = Actual dimension / Drawing dimension = 16 in / 5 in = 3.2. Now, you can apply this scale factor to dimension A. Actual A = Drawing A × Scale factor = 3.75 in × 3.2 = 12 in.

Now, for the scale factor, we previously found it to be 3.2, which means every inch on the drawing represents 3.2 inches in reality. This scale factor is essential in technical drawings for accurate construction and manufacturing, ensuring that everyone is on the same page when interpreting the designs.
