Re: Tension Stress Graphs

Bill,

Thanks for your response.

I didn't word my comments properly.

The engineer has already produced these graphs.

I'm attempting to interpret them.

I'm just not familiar with "tension stress graphs" per se.

But I will probably become an enlightened expert in a few days.   ;o)
