For 4 buckets, the total weight of one bucket and rope needs to be at least a little bit over 25% the total weight of the table and rope. All 4 buckets total is 100% the weight of the table, plus a bit. The buckets overcome the weight of the table (and rope), go down and lift the table and eventually come to a stop on the surface of the table itself. Elementary, my dear mavaction!
If:
N = total # of buckets
N[SUP]m[/SUP] = total mass of buckets
n = 1/N
n[SUP]m[/SUP] = n * N[SUP]m[/SUP]
T = total mass of table
t = n * T
r[SUP]a[/SUP] = mass of rope on bucket side of pulley
r[SUP]b[/SUP] = mass of rope on table side pulley
R[SUP]a[/SUP] = total mass of rope on bucket side of pulley
R[SUP]b[/SUP] = total mass of rope on table side of pulley
Q = Unknown additional mass constant to overcome equilibrium and friction coefficient of the pulley and the rope. See "little bit" above. (lol?)
q = n * Q
S[SUP]a[/SUP] = total mass of bucket side of pulley
S[SUP]b[/SUP] = total mass of table side of pulley
then to see results like in the picture:
S[SUP]a[/SUP] = N[SUP]m[/SUP] + Q + R[SUP]a[/SUP]
S[SUP]b[/SUP] = T + R[SUP]b[/SUP]
S[SUP]a[/SUP] > S[SUP]b[/SUP]
n[SUP]m[/SUP] + q + r[SUP]a[/SUP] > t + r[SUP]b[/SUP]
N[SUP]m[/SUP] + Q + R[SUP]a[/SUP] > T + R[SUP]b[/SUP]
Q > T + R[SUP]b[/SUP] - R[SUP]a[/SUP] - N[SUP]m

I didn't get it at first but after reading Jacks explanation it is so simple. God, I'm such a dope sometimes :facepalm:
You are both wrong. Your physics teacher in college must gave hated you. Oh wait.
TV is on the wall behind the guy taking the picture. The buckets are filled with cashews for the domino game.
push the table down 1 inch buckets would go up one each .... same weight balance
