Can anyone please help? See link for sketch and calculations.

I have a M30 x 150 long stainless steel stud fully welded to a base plate that is under a load of 12.5 ton = 122583 N.

Using Cantilever beam theory I have produced two different sets of calculations using point load and UDL to see a comparison between the results.

Firstly can you please advise I have calculated these correctly?

Secondly, I have calculated the maximum bending moment to be -17774.5 Nm, How do I calculate what the maximum allowable bending moment for the M30 x 150 stud size?

Also for the maximum deflection and slop results, how can I calculate the maximum allowable deflection and slop?
I’m also unsure if the slop calculation is necessary for what I am trying to do which is to make sure the stud can withstand the load.

I’m a first year apprentice in mechanical engineering and it’s in my own interest to learn all this kind of thing because I have an opportunity to learn FEA later in the year.

Please help

The maximum allowable bending moment for the M30 x 150 stud size depends on the material, grade, and other factors. You can consult the manufacturer's specifications or an engineering handbook to determine the specific value. Additionally, you can use a finite element analysis (FEA) program to calculate the maximum allowable bending moment for the stud size. The FEA program will also give you the maximum allowable deflection and slope values.
