[DeTomaso] Engine Bay Brace question

[Dick Koch]

I may be repeating what I believe Goran said but the "truss" that GW 
shows in his pictures is unstable. 

While there are some benefits in adding the two "45" degree members to 
the top and bottom braces to stabilizing the two horizontal braces, the 
effects are minimal as compared to employing the triangulation rules of 
truss design.

As everyone knows on this forum from what they learned in grade school 
geometry, the only stable two dimensional shape is a triangle. 

Basic force vector analysis of truss design requires that all load 
points be triangulated. 

Leaving out that there are more than 2 dimensional forces involved in 
stabilizing the rear suspension mounts and if one where to design the 
"optimum" rear suspension truss (which I think is a waste of time and 
overkill), a designer would  build a three dimensional truss.

Some basic reference material can be found on many online sites that can 
provide some "put you to sleep" material over the Christmas and New Year 
holidays, such as:

To all, have a Merry Christmas and a Happy and most important for the 
older folks on this forum a Healthy New Year.
