Need a help with a rigid body analysis

[Black0058]

Have to complete the analysis of a rigid body of a dining table which is having a single cylinder at the centre of the table which is made of Sheet metal and the above table plate is made of granite I need to find the results for when a 60-80 kg load is applied on the one side of the table it will stop or wobble so I need to find how much weight and material should be used to measure the weight which will counter the wobble and stop the wobble by adding weight to base so how should and what should I do in ansys to find solution for it?
I attached a file below where I did the simulation which I knew but this is not the solution they said so I need to find the solution on a rigid body where only counter weight and material to stop the wobble should be used

You may have missed a step - there is no attachment.

I can barely follow the words ... can you post the question (as written) and your solution attempt.

don't double post. click the "report" bell and ask to have this thread deleted.

Your original post included a STEP file, which is not particularly useful, unless your audience all have STEP file reading capability. A screenshot would be much better.

Does the assignment require only adding weight? The base diameter would be typically the thing to adjust, since if you make the base larger than the diameter as the table top, weight of the base is almost irrelevant, assuming it's stiff enough. The smaller the base the more weight of the base becomes an issue. If the base is the same diameter as the cylinder, the weight will need to be significant.

You can look at it from the point at which it does "wobble" (tip over?); at that point, the table is balanced on a single point, and the tipping point is the counterbalance of the weight and lever arm of the tabletop vs. the weight and lever arm of the base, i.e., when the center of mass is outside the balance point of the table.
