Just realised something don't know if it makes a difference to your understanding,
The sketch including moment calculations only represents the "sliding part" on top of the main beam. Basic statics I guess again, but is it more logical to represent the reactions calculated on the top part in...
Many thanks guys,
Ya basic statics I am still learning, I see it becomes very elementary for guys like you which is nice to see. All of you have been very helpful I'll be crunching up some more with your help!
Thanks a lot

Why is your max moment 130kN.mm?
I understand what you mean with the component moments and having the angle in this position was one of the challenges I realised.
Since we're using a unit tension, where does it come together that I have the official 'max value' if my calculations are based on...
Please be more clear on the following : unit tension? Isn't that what I did with my "1KN" ? Here's the sketch I did.
Also : fcy? and how do I calculate the stress your speaking of from your unit tension. These are the steps I'm confused with...
I did a simple calculation to find a proportion of the moment transfered to the beam with respect to the tension felt ( Set as 1 ) which is why I consider it a proportion.
So when I find the maximum "momentum" that can be applied at different points I can know how much that means in tension...
After putting some thought (as this is new to me) I agree on the conservative nature of such an approach. But I'm still stuck at the same step, what are the first steps involved in this when you want to work backwards? (Knowing the maximum force the beam can take at anypoint)
I might have a bad conception, and please correct me if I do, but the beam is "bolted" onto the lower beam, which I realise is not the same as 'FIXED' in structural terms.
@BAretired,
The beam IS fixed at both ends it was hard to represent it as so but the "V" beam or angle beam is bolted onto the beam under it, which is bolted into concrete, the values as I said are for now unknown as the goal is to determine structurally, the maximum load this beam can allow...
What were trying to find out in our scenario is the maximum tension this beam will allow before failing. Basically I don't have a value for the tension available, but we need to rate the maximum allowable tension for this ass'y on the plans sent to the company using it.
There are two beams yes...
And no it is not a motor sitting on it, yes the assembly is a belt tensioner but it is just a pulley, the drive assembly is separate, this part adjusts the tension on the belt by moving the pulley up and downwards a little like some bend pulley's in vehicule driven accessories.
Here is the "sketch" I made showing where I want to start at the basics!
Basically the beam I'm analysing is fixed at both ends, and my understanding has it that we are applying a moment force to it because the bender has tendancy to "spin"...
Just a little insight on me, I'm currently working for a company as a student they give me little projects but don't have much time to help me with them I'm a little stuck on this one help would be very appreciated.
Ok so this is the "real setup" on the sketch, the pulley has a travel distance...
