Okay
Here comes a picture. The 70*70 stud should be moved precisely to the right of the drainage pipe.
Thanks

Hi
I am going to brace a roof truss? on the upper floor of a townhouse. What currently supports the roof truss is a vertical 70*70 stud standing on a door post 45*210. I am going to move the stud 50 cm to the right and place a horizontal beam to brace the roof truss. It continues on the other side about 1.2 meters and attaches there to another supporting stud. My question is how thick the horizontal beam needs to be. I have bought a board measuring 70*120 and wonder if perhaps 70*90 is enough since it affects how much I need to lower the ceiling.
Very grateful for an answer!

In a question like this, I wouldn't want estimates or educated guesses. Talk to a designer about this is my advice.
When you fiddle with things you don't actually know much about, you have to over-dimension. I wouldn't dare to lay as slender a beam as you're talking about horizontally. The fact that a 70x70 supports everything today cannot be compared to because a wooden stick handles enormous loads lengthwise, but does not have the same ability sideways.
Here you can see how I've done it, I would do something similar if I were in your shoes:

An alternative if you want to avoid a visible beam is to place the beam on top of the truss and hang the same from the beam.
Also, think carefully about how you take up the load downwards, i.e. the bearing for your posts. It is probably possible to copy the existing solution for the two new posts.

Hello again and thank you for your feedback!
I wasn't very precise in my measurements. Some more exact measurements are 1 meter on one side of the center of gravity and 0.5 meter on the other side. So the beam will be a total of 1.5 meters.
One thought I had was that perhaps you notice how heavy the weight is from the truss when setting up the supports.
Grateful for all your feedback!
