do you even know what stress means? you dont disperse stress. Stress is caused by something. you cant go outside one day and say hey i think im going to disperse the stress on this will. you freakin dummy.


You can disperse a point load, which I what I'm sure LCA meant. By spreading that load over a larger area, you effectively decrease the stress (force/area).

BTW im wondering what yall mean by an unsupported brick wall. I mean it is a wall. It is supported.


The bricks are stacked on top of each other and joined by mortar. They are attached to nothing else.

Inommmm, it must be put in simple terms.

Ramrod, if you have fallen off your bar stool again and are lying flat on the bar floor again, and a woman with a stiletto heel steps on the back of your hand, it will most likely break a bone. However, if she were wearing tennis shoes, the stress on the bone in the back of your hand will be dispersed to the width of the tennis shoe.

True, but over the entire wall, that is a lot of both brick and mortar. Plus you have the hearth connected and what looks like some back space (from the fireplace and the wood storage helping to form an upside down T. Just by its shear weight and wide base, the wall is more than capable of supporting a TV. Like I said before, if there is a concern that the TV is going to bring down the wall, we got bigger issues that need to be addressed first!

If the brick or more so the mortar and mortar bond to the brick is sound, it would take a lot more than that TV to tear out even a single wythe section of the wall.

The bricks are probably three hole, and the mortar not only bonds them together but also keys them together via those holes.

Actually, how thick is the wall? Is it one brick or more thick where you are mounting the TV?
