hi richard,

i modeled in caeser to check the stresses, forces, moments for 12" - STD shd, Insulation 2", Material A106 Gr B


from node 10 to 20 DX= 11 ft, anchor at node 10.

then i have FY= 626


MX=0, MY=0, MZ = 4333. MY DOUBT IS THAT HOW WE GOT MOMENT IN Z DIRECTION AT NODE 10.


PLS HLP ME

Simple, you have a cantilever that have "Weight" and is oriented on x axis. Hence you have MZ.

Before anything else, please read again your university courses "strength of materials".

Regards,

If it is an 11 foot beam that should weigh 626 lbs, the CG should be at 5.5' away from the anchor.

5.5 x 626 = 3433. You cite 4333, is that a typographical error on your part, or is that really 4333?

It was a typographical error on his part. Good eye. It was 3443.1.As being so simple, I reconstructed the model.

In this way you performed also the program validation.

Best regards,

And Michael, guess what. 5.5 x 626 = 3443 not 3433


Regards,

Shame on both of us.
