The scale written in the right side of the drawing shows the true length. Any drawing has perspective, but to determine the length of the specifications, one must have the actual scale by the designer. This is always defined by the draftsman and noted somewhere either on the right upper side corner or the lower right side corner.
The scale factor of a scale drawing is the ratio of any length in the drawing to the true corresponding length in the "real" object.
the answer is 12.

I would understand that to be a drawing that shows true dimensions from three views. Engineering uses this to define a part. It usually has the object viewed from the 3 sides.

Used in the fabrication industry as the center diameter of the thickness of the material that has to be rolled in to a tube or as we call it "a Can" and to calculate the true length in the flat. ex: Using .25 thk. plate rolled to a 48" I.Dia. take 48.25" x TT (3.1415) = 151.5818" long or the true length to roll to a 48" I.D.

Without getting into all the math, the engineering strain utilizes the initial length of the specimen in the calculation, the true strain utilizes the instantaneous length of the specimen.Getting into the math:strain engineering = change in L / original Ltrue strain = ln(1+strain engineering)Engineering strain is the change in length divided by the original length, so that a 1 inch part strained 50% or .5 in/in would become 1.5 in or if strained -50% or -.5 in/in would become .5 inches. But these two strains are not the same amount of deformation since as a material is stretched further the change in length is distributed over a longer length for positive values and over a smaller length for larger values. Consider progressing from the now 1.5 in. (50%) strained part and continuing to 100% and the .5 in. (-50%) strained part and continuing to -100%. The next change in length is distributed over 1.5 in. and .5 inches respectively despite this the equation considers this change relative to the same original length of 1 inch. True strain is the change in length divided by the instantaneous length integrated from the original length to the instantaneous length. This resolves to the equation above.
