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.
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?
