It's been a strawberry floating tough couple of years but it feels good right now. Mini E - you're next up to join the GRCade Doctor club, good luck with the last stretch of yours! :D

Tomorrow I have a lunch with a former student's bereaved family who took his own life.

That student scenario is literally my worst nightmare - good on you for meeting the family, it sounds like you’re going the extra mile there and deserve your teaching award!

Not sure where to post this, but this is from Roark stress and strain, elestic beams;

Does anyone know how to derive the formula for the moments MA and MB?

Ive tried resolving moments about both ends and the load point, but end up with the same formula and 0=0.

I think i must be missing an equation?

EDIT: Solved. I posted this on an engineering forum and managed to get the solution before i seemed to get banned (maybe for the image?)

For those interested its a statically indeterminate problem, so you have to consider a cantilever and determine the slope at A with the load, then apply a moment at A without the load and get an expression for the slop at A, then superimpose the 2 cases and equate the slopes to zero.

Has anyone ever written a publication plan?

I'm applying for some data and the organization is asking for one, and I have no idea how long it's supposed to be. They ask for it as part of a web form, so part of me thinks it should be very short, but other parts of the form have a 1000 character minimum, not this part though, so maybe it should be longer?

I have achieved Candidacy. :toot:

Also, I ended up getting that data that I mentioned in the post above. :toot: :toot:

Now I have a statistics question, I'm sure this is very basic but I just wanted to get your opinion.

I want to look at the variation of a variable in a population based on some different characteristics (for example variation in height for males vs. females, under 20 vs. over 20 etc). Would an independent sample t-test be the best for this or is there any other test I should look at?

an independent samples t-test will give you a p value to determine whether the two groups (male vs female) are statistically different in height I would think... but if you're looking at the variation of a variable, would just using standard deviations not be easier? I may have misunderstood your question :)

Congratulations on the candidacy!

Thanks!

Also, I thought using the t-test would be better as it will be able to tell me if the differences are statistically significant, no?

Potentially use an independent t test for significance and Cohen’s effect sizes to demonstrate the size of the difference? You’ll get your sig. from the t test, yep.

Been ridiculously busy with the Ph.D. over the last couple months. Right now it's almost 11 and I've only just left the office :lol: :cry:
