Does this look reasonable? Partly an academic exercise...
Single skin internal solid brick wall Single storey, non load wall (so nothing sits on top - ceiling joists run parallel and either side)
TV mount 0.8m down from top of wall and about 0.6m from the corner, doorway 0.6m to the right of the TV mount mid position.
Cannot verify if this wall is tied to the main outside wall (left of diagram - probably is as both are brick and 1950s build??
Blue bricks take the fixing bolts. Green bricks show what I think are the bricks whose weight transfers onto those blue bricks.
There are 105 blue/green bricks at 2kg/brick and assuming 0.5kg mortar+plaster per brick.
So for the TV to be able to tip that wall over, even if it was dry stacked loose, would require 165Nm or turning moment assuming:
105 brick's worth of weight acts vertically downwards in the centre of the wall and the bracket is 1/2 brick+10mm plaster away from the centre.
TV is 11.4kg, soundbar is 4kg, 50% of the TV bracket is 5.5kg, so total load at 600mm (max reach of bracket arm) is 200N rounded, with a turning moment of 120Nm < 165Nm
In reality the limited adhesive effect of the mortar will add strength, the wall is probably (should be) tied to the outside wall on the left so that will resist toppling and there is a heavy wooden sliding door hung on the otherside of this wall (goes behind the TV when open) so that's counterbalancing too.
Thoughts on method and assumptions?
