I found the following image in one of the Apple’s Interface Builder tutorials for iPhone programming. I have this habit of skimming through the whole page before giving it a concentrated read and after seeing this image, thought “Wow… Something explained here in relation to two poular web frameworks “Struts” and “Springs”… But but, i am in Interface builder tutorial… What is happening here???… “
After reading what they are trying to say in that section, I realized they mean what plain english word means when you say “spring” and “strut”…
But, I felt this as a rare coincidence to see these words together in the least expected spot 
Struts & Springs
The older versions of Interface Builder used a bit more literal graphics, as you can see here: http://katidev.com/blog/2008/02/12/why-i-say-no-to-autoresizing/
