A couple of weeks ago there was a posting about using
1 x 2 4130 for a front shertz beam motor mount and if
it would be strong enough without bracing to the
engine. I never saw an answer to this.  Can someone
fill me in.  Thanks Jim Coffman

Bill Schertz, this is all I could find searching the old messages.
Do you have the calculations in plain text form?

Here is a two page PDF that has the diagram and explanation that doesn't
require Excel. 21K file size. The bold line is the design that I went with.
2 x 1 x .065 out of 4130 steel, with aluminum ends.

OK Bill, my mistake apparently xv was able to see the first gif in the pdf file
for some strange reason. This works.
