OK.
So now we're going to look at the free body diagrams in order to get the remaining information we need
to calculate our various different diagrams that we need to summarize our analysis.
So the first free body diagram I'm going to look at is for a member of B E.
So taking some of the moments about me.
And so VB lower is twenty six point five four kill in humans.
Now these some of the forces in the horizontal direction must be equal.
And so we can say by inspection hate.
He is also twenty six point five for Killen reasons in the opposite direction to the be lower which
is in the direction shown.
So moving not married C.
Some of the moments about Point B must equal zero.
V.s. Owl the e.s. Left is forty four point four six killings.
Ms.
Therefore.
Easy be or will be 75 minus forty four point four six council v.b. or is equal to thirty point five
for keelen indians.
Both of those shares shears acting OK as sharne.
Okay.
We'd like to know the moment underneath the point gloater will do a course at that location.
So taking the sample of the moments about the court.
And that will cause tension on the bottom.
Soul member acg.
Both of those in the direction schaad.
Okay so moving on to member C F.
OK so taking the sohmer the moment about point f to determine E V E C lower.
And so these C lower is equal to forty three point nine nine.
Kill any patterns in the direction qod and taking these the forces in the horizontal direction also
equals zero.
We can evaluate that hate sheth is equal to 20 Killian's promesa acting over 6 measures minus white
forty three point nine nine.
So hey Jeff will be seventy six point o worn.
Kill any of.
Again in the direction sharne and we'd like to work out where he maximal moment is and we know at this
stage that the max moment.
Occurs.
Let's take the horizontal force at the bottom.
Seventy six point are worn divided by the rate at which that reduces will give me three point eight
meters.
That's the point I wish the sheer force zero which is also the point of maximum moments.
So that's a ball of f right and so we know where to make the cut.
So taking some of the moments of the course.
And so M. Max Here's forty point one eight Killen hidden meters causing tension on the right hand side
of the elements.
And the last member we need to consider is member at saeedi.
So taking the sum of the moment to pay Dee.
So v.c. or is it fifty three point four.
Kill any evidence.
And therefore vdb is gonna be 75 minus fifty three point four.
And so weedy is twenty one point six kilotons.
Also acting up as expected.
I'll keep working at this spam moment any moment.
Underneath that point load.
Sell em.
SPAN taken some of the moments about the Kosh MS impact would equal fifty three point four times a lever
all three minus ninety five point three.
Nine killed it metres.
And so Ms span is equal to sixty four point eight.
Worn kill innocent meters.
Okay so we're finished with free body diagrams.
Now all we have to do is capture or summarize.
Are all of that information from our analysis into you our relevant diagrams.
So looking at the sheer force diagram first.
Well Kate moving Aren't you the bending moment diagram.
So that wraps up our bending moment diagram.
Now we're gonna move on and do the final diagram which is qualitative deflected shape and we're gonna
do exactly the same as we've done in every question.
Up until this point we're going to look at the information we already have and really the main source
of information for determining or for drying out this deflected shape is going to be the bending moment
diagram.
That's where we get the bulk of our information on how this structure is going to bend and behave under
loading.
K so we know we have tension on the right hand side.
This member so we know it's going to curve down.
Like so the tension on the right.
We know the whole structure it sways to the right as well.
We know this lower member C F starts off with tension on the left very quickly changing to tension on
the right before returning to tension on the left sorgono how something like this.
So here have tension tension and tension.
You can quickly see that this mamber to flex like so.
We're going to have tension cross at top.
Okay so that moralez captures the picture as far as deflection for this structure.
In those last three diagrams we have more or less wrapped up the complete analysis for this particular
frame.
We summarised everything over the preceding number of pages to represent the sheer force bending moments
and an estimate of the fact that shaped so that moralez wraps up that question.
