A scale factor is a ratio of one length on some geometric figure compared to another lenth on a congruent geometric figure.\nFor instance:\nYou have squareA with length of side 4 and squareB with a length of side 8. The ratio or scale factor from squareB to squareA is 2. The scale factor from squareA to squareB is 1/2 or .5.
It doesn't hurt to be inquisitive on Yahoo Answers and get sources of information for stuff you are doing for your engineering homework.  As long as you aren't posting questions directly from your homework and as long as you actually use this as simply a starting point for your research, keep up the good work.\n\nAs far as Electrical Engineering stuff.  I have found what I needed a few times from Google.com and Wikipedia.  However, that is a difficult course and I would recommend tutoring or study groups if you are struggeling.  \n\nGood Luck.
