AI Thread Summary
Using a wood shelf on top of a TV stand may help distribute the weight of a heavy TV, but concerns about sagging remain. Reviews indicate that heavy TVs can cause the center of the stand to sag, particularly due to the design and materials used in the stand. The IKEA shelf could provide some support, especially if it is wider than the central gap in the stand. However, the structural integrity of the stand may still lead to eventual sagging, especially with the weight concentrated in the middle. A wall bracket for the TV is recommended for better weight distribution and to prevent damage to the stand.

TL;DR Summary
Trying to determine if putting a wood shelf on top of a TV stand will distribute the weight of a heavy TV enough to prevent sag in the center of the top board of the stand.
This is the TV stand I want to buy: https://www.wayfair.com/furniture/p...vs-up-to-80-w004939229.html?piid[0]=818726787

But reviews said heavy TVs cause the center of the top of the TV stand to sag (shown in photos in one-star reviews).

I own a 77-inch LG C3 TV that has a stand at its center.

I also own this IKEA lack shelf: https://www.ikea.com/us/en/p/lack-w...cks_Store_and_organise_furniture&gad_source=1

I plan to put the shelf on top of stand and then the TV on top of the shelf.

My question: Will the shelf will distribute the TV's weight across the entirety of the stand's top so it doesn't lag in the middle?

In theory it will help, especially when the extra board is wider than the central gap in the stand.

At least as long your heavy TV doesn't break through this: "Filling material: Honeycomb structure paper filling (100% recycled)"
 
Welcome, @whitecollar23 !

It seems that it will sag eventually.
The location of the two vertical partitions is bending the bottom horizontal panel (note location at leg-leg midspan).
Then, that bottom panel is forcing the top panel to deform via the end vertical panels.

I would use the wall bracket of the IKEA shelf and support all the weight of the TV from the wall.
A dedicated TV wall bracket would also work, providing a cleaner solution.

Thread 'The Effect of Linear and Rotational Motion on Measured Weight'

Consider an extremely long and perfectly calibrated scale. A car with a mass of 1000 kg is placed on it, and the scale registers this weight accurately. Now, suppose the car begins to move, reaching very high speeds. Neglecting air resistance and rolling friction, if the car attains, for example, a velocity of 500 km/h, will the scale still indicate a weight corresponding to 1000 kg, or will the measured value decrease as a result of the motion? In a second scenario, imagine a person with a...

Thread 'Coulomb gauge implies instantaneous radial electric field?'

Scalar and vector potentials in Coulomb gauge Assume Coulomb gauge so that $$\nabla \cdot \mathbf{A}=0.\tag{1}$$ The scalar potential ##\phi## is described by Poisson's equation $$\nabla^2 \phi = -\frac{\rho}{\varepsilon_0}\tag{2}$$ which has the instantaneous general solution given by $$\phi(\mathbf{r},t)=\frac{1}{4\pi\varepsilon_0}\int \frac{\rho(\mathbf{r}',t)}{|\mathbf{r}-\mathbf{r}'|}d^3r'.\tag{3}$$ In Coulomb gauge the vector potential ##\mathbf{A}## is given by...

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8 and stuck at some statements. It's little bit confused. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. Solution : The surface bound charge on the ##xy## plane is of opposite sign to ##q##, so the force will be...
