A quick follow-up on my previous post... While researching this a bit more, I found a very interesting engineering document on the mechanics of landing gear systems:
http://www.mecheng.adelaide.edu.au/~marjom01/Aeronautical%20Engineering%20Projects/2006/group11.pdf The PDF is just over 6mb in size, but well worth the download. There are very good descriptions of the mechanics involved with different gear systems--and included is some c172-specific information as well, in Chapter 8 (Page 38). The author also shows a calculation showing that a typical nose strut in a 172 compresses about 9.3" on landing.
