In response to the thread about crank-up tower failures I put some selected
output views from a finite element stress analysis of my LM-470 loaded to
theoretical yield failure at: http://www.flukey.cc/km5vi/finite%20Element/
The analysis indicates the theoretical points of failure where the peak
stress exceeds the material yield (for this tower 42,000 psi). As someone
stated, these points certainly are not at the lower tower section.
