 Cantilever Structure (Posted on 2010-02-26)

The cantilever structure shown in the figure consists of 4n-1 struts of the same length plus one that is half that length. Each strut can handle a maximum tension force T before it will snap and a maximum compression force C before it will buckle. The structure is connected to a wall at points B and C. A weight W is attached at point A. The weight W is increased until two struts fail - one from tension and the other from compression.

What is the value of the ratio C/T if n = 25?

Consider the struts as weightless.

I have such a one track mind sometimes - as Bractals pointed out in his comment, I didn't really answer the question.  The true answer is 0.98, based on the analysis in my earlier comment.
