Table held up by buckets resting on it.

just a guess, statics was a long time ago



Your equation is ΣF=0
Start with a Free Body Diagram. Since it's static the sum of all forces must equal zero. There's some "ΣFb≥Fw" crap you can throw in here too, but I'm not going that far.

They should use legs so they can have big booty hoes dance on it instead. Mine> buckets.

HA!

[TexasDevilDog]

you seriously are putting that much effort into this?

the buckets together weigh more than the table. This is a piece of artwork, and I seriously doubt that they are sitting there without being attached to the table. If it wasnt nailed down, someone *could* bump it and there would be a mess.

In conclusion: all of this is bullshit, and texasdevildumbasss is still an idiot.

You ask for enlightenment, then ignore the answer and attack the answerer. I imagine the same response from Neanderthals to fire.

I asked? Where?

The foundation of the building is holding it all up.

I'm waiting.

I am the object of your anticipation.

You two need to get a room.

Good God you really are that stupid.

Dammit, can someone just get Ruffdaddy in here to settle this!

BTW, I'm retracting my first free body diagram post. I ain't too proud to admit that rather than just using my eyes and brain I went all mathy on it TDD style

My intuition is better on electrical circuits than with mechanical. I am not too proud to draw pictures and do math.

Since you quoted me I'll repost it. I know what my intuition says, but I just don't care to math

Sorry that most of you can't understand that there is only one equation that describes this problem with three unknown variables; bucket mass, table mass, angle of the rope. That leads to answers found with boundary conditions.

I am sure that everyone on here smarter than me will be posting their picture of their math proof contradicting my math proof.

As far as I'm concerned no one needs to post any more math, because it's much simpler than anyone made it. A single redirect pulley only changes the direction of force; it does not change the magnitude. There is no mechanical advantage (or disadvantage) in a single pulley. I should not have had "sin theta" in my FBD.

Now the reactant force on the pulley where it's anchored to the ceiling will change, but if you have 100 lbs in the bucket and pull straight down (180*) or horizontal (90*) across the pulley it will still only take 100 lbs of force.




So I say "as the angle approaches zero" none of the math matters. When your downward force (table weight) overcomes your upward force (combined bucket weight with direction changed via pulley) the table will lower.


Here's your "angle approaching zero" situation.




No matter the angle, with a single pulley your force does not change.




And if I'm wrong, well fuck me. I don't get paid to do this.

And I see another error in my ways. I'm out.
