How to calculate the weight of a TV, mounted on a different type of brackets and positioned at different swirling angles?
The problem:
So basically I want to calculate the weight/pressure of TV that I want to mount on my wall so I can on my own later on find the right anchors, right fittings, and TBH I am interested in getting a formula on this one. So I will represent some of my sketches and thoughts and questions about the problem, but all in lay-man terms as I don't know else. You will see a lot of kinda non-physics related images, but those are for showing where the pressure point of both the mounts are, so you can get a better picture. I really tried finding an answer before questioning, but I couldn't with this particular use-case.
The trick is the following, I am looking for a mount that is capable of doing 90 degree swirl to one side, basically making the TV perpendicular to the wall. This means the mass of the TV will not have the same effect to the wall if it was parallel without an offset like usually. Another thing which makes me think about this problem is that my walls are constructed of vertically perforated brick, not a solid brick or consisting wooden wall studs, so I wanna make sure everything will be fine.
So by different swirling angles I mean from 0 to 90 degrees on a side, by different type of brackets, is the most interesting part for me that I want to figure it out which is having screws positioned on a horizontal vs vertical plate, and what would be the strongest.
The examples:
I am taking two mounting brackets, here are the images of a sketch with all the dimensions needed of both types.
The horizontally positioned mounting bracket that can swirl 90 degrees to a side:
The vertically positioned bracket that can also swirl 90 degrees to a side:
also I found another more detailed picture from the vertical one, it has screw hole distances and such, some holes are not correct, I will mention this later on, but in my physics question I think it doesn't really matter.
The questions (my concerns and current understandings):
As I already mentioned, I want to find the right anchors types and sizes which would be much more easy if I find the weight of the TV in few positions. I'll ask in two parts.
So first, without dictating the mounting bracket environments, how much weight does an rectangle which we would call a TV put to a line, which would we call a wall.
TV mass = 20 kg
TV width = 110 cm
1. 229
How much weight does the TV put on the wall at a parallel non offset setting?
2. How much weight does the TV put on the wall at a parallel 60 cm offset to the wall setting. Note that the TV is mounted in the center of the bracket handler?
3. How much weight does the TV put to the wall while being perpendicular e.g swirled at a 90 degree angle to the wall?
4. How much weight does the TV put to the wall while being perpendicular and swirled at a 45 degree angle to the wall?
So basically I want to get an understanding of the formula that goes into this. Here is my visual representation of the first 3 questions.
The second part and that is how would each type of mounting bracket (or connection) affect the weight of the TV to the wall.
The first bracket has its screw holes placed on two horizontal lines, here is a picture:
Now I know that the pressure will be on the top screws so I can put more screws there compared to the bottom, and I thought this was a clear winner, which probably might be, but after realizing the following for the vertical bracket I am not sure for what difference.
So the second bracket is a vertical screw setup and as I mentioned, in one of the pictures it is not shown correctly, it actually looks like this:
I was sure that the vertical bracket was worse than the horizontal bracket before I realized that the vertical one also has middle section with 2 screws:
Now we can also assume that even tho there is a middle section, the hands of the bracket are not actually directly connected to that part, but it still gives some leverage. As we can see from picture 2 or 3, the vertical section is about 40 cm in length or should I say height. This middle section length is about 8.6 cm as seen in picture 3, and it is right in the middle of the 40 cm bracket, with two screws above the middle and beneath it, this I guess gives a much, much better withstanding strength then if it were just the top and bottom two screws. 441
