I have no idea on how to start these two problems. I haven't done any work, but please give me some hints on how to get started. The two problems are here http://viewmorepics.myspace.com/index.cfm?fuseaction=viewImage&friendID=128765607&imageID=1461065539 For problem 14, the anskwer are 1.2kg, .3kg, and .1kg for 15, the answers are 54.9N,95N,170N. For problem 14, I know that the right of the wire extends 3 times as far to suppor the penguin. It appears to me that we divide the mass by four each time with the exception of the last time. What is the reasoing behind it? For 15, I really have no idea. Maybe it's because I don't really understand the question.
