Because the three feet of the tripod are on the same plane, even if one leg is shorter it will not waver or stumble. However, with four legs, if one leg is shorter it will end up in two planes, or two tripods, and will always waver from one plane to the other, thus making the chair/table unstable. Chairs and tables are probably four legged because they are rectangular. If you want a three legged table you would need to have an extra sphere/block that has three legs branching out, and it would be more expensive.

Why is a three legged stool not rock as much as a four legged stool?
Three points are the minimum required to define a geometric Plane. Any 3-legged stool, then, can only exist on a single Plane, and cannot alternate between any two Planes (i.e., rock). By combining any 3 of the 4 or more legs on the stool could define a separate plane on which the stool could stand. There are 4 separate configurations of 3 legs upon which a 4-legged table could stand: ABC AB D A CD BCD
Why does a three legged support work better than a four legged one?
Three points determine a plane. To put it another way, a plane can always contact any set of three points. So the tips of the legs of a 3-legged support always contact the floor. A 4-legged support has four possible sets of three legs, i.e. four possible planes that it can contact. Unless all four legs are exactly the same length, their ends don't all lie in the same plane. When set down on a single plane ... like the floor ... the support winds up wobbling among different sets of three points.
If perimeter of a square table is 12 feet What is the lenght of each side of the table?
In a square, all four sides are of equal length. Divide the perimeter by four to find the length of each side: 12 ÷ 4 = 3 ft
Raj builds a side table in the shape of a cube. each edge of the cube measures 20 inches. raj wants to cover the top and four sides f the table with ceramic tiles. each tile has an edge length of 5 in?
He will need 80 tiles.
What does each shape of conference tables mean like kidney shaped oval triangular trapezoid?
These words are all quite self-descriptive, so I wonder what kind of answer you seek. A triangle is a 3-sided figure-- very unusual for any kind of table. A trapezoid is a four-sided figure, like many tables, but requires only 2 of the sides to be parallel- again a very odd shape for a table, except for the special case of trapezoid, called a rectangle. An oval is a circle with one axis stretched out- a common shape for a dining table, but not likely for a conference table. since it does not fit neatly in a rectangular room. Kidney shape is like a kidney or a kidney bean- like an oval that is bent and pressed in at the middle- not a common shape for a table.
Why does a 3 legged support tripod work better than one with 4 legs?
If the surface on which it sits is slightly uneven, then a three-legged support will still sit stable. However, on an uneven surface, a four-legged support may wobble.
Why does a four legged table rock from side to side?
Either the legs are not secure to the frame, or the table is not level.
A carpenter knows a four-legged table can wobble whereas a three-legged table will not?
Yes. This is because any three points will always be coplanar, but a fourth point may not be.
Why do you think are we less stable than four-legged mammals?
Humans balance on two legs. This is less stable than balancing on four legs. The more legs you can lean on, the more stable you are. Centipedes are really stable!

Why is three legged table stronger than a four legged table?
A triangle is the strongest geometric figure It is not necessarily stronger but it will stand on the ground on all legs when the ground is uneven, unlike a table with more legs
What is the function of the tripod STAND in science?
The tripod stand in science is used to support equipment, such as beakers, flasks, or funnels, over a heat source like a Bunsen burner. It provides stability and prevents the equipment from tipping over or directly contacting the heat source. The adjustable legs allow for different height settings to control the distance between the equipment and the heat source.
What's the difference between a bedside table and a nightstand?
A bedside table is a simple four legged table, while a nightstand is more akin to a cabinet or drawer chest.
Why is three legged stool stronger than a four legged chair?
it isnt It is not stronger. True, a 3-leg will not wobble because 3 points define a plane. However, a 3-legged table will tip over more easily than a 4-legged table. I suspect some science guru has done the physics on this and can prove what I say.
Is three legged chair more stable than a four legged chair?
On a four legged chair, if any of the legs are not as long (or longer) as the others, the chair will wobble. On a three legged stoll, if one of the legs are different, the chair will only be uneven or fall over (depending on how drastic the difference is).
What is another name for a four legged animal?
Another name for a four legged animal is a quadruped.
How many four legged animals are there?
There would have to be trillions of four-legged animals that exist on Earth.
