It depends on the density (the mass per unit volume) not just the weight. That is why a one ton anchor sinks while a 100,000 ton ship floats.
14lbs. try it.
The amount of weight a curtain rod can support depends on how many support brackets are helping support it. The more supports, the more weight. If there are no supports a typical rod can hold 20-30 lbs.
There are two main reasons for a dam's broad-base design, and both are explained by the fact that all materials have limited strengths. The only practical way to increase strength is by adding material. The first idea is that a dam has to support its own weight. The heavier a dam gets, the more material is needed at the base to support itself. Hence very large dams have enormous bases. The second idea is that the dam has to also support water behind it. The top of the dam is thinner because it does not have to support too much water; only the surface of the water needs support. But as the water gets deeper, the dam has to support all that water above , and then its own weight. At the bottom, the dam has to support all the water and its own weight. This means that as you get lower, the dam has to get stronger. And as mentioned above, the only practical way to do so is to add material.
There are several ways.It could be made of one of the metals that actually do float on water: lithium, sodium, and potassiumIt could be formed into a shape that spreads the weight around so much that the water will support it, such as a boat.
That all depends on the construction of the floor, do it badly enough and it won't even support itself.
The cylinder will support, at neutral buoyancy, as much weight as the weight of water it could contain, less the weight of the cylinder itself.
1 cubic foot of air will support 62 lbs
not much
it can hold as much weight as it can handle
14lbs. try it.
A two by four can support a load up to 400 pounds. The length of a two by four will change the weight it can support.
The amount of weight a curtain rod can support depends on how many support brackets are helping support it. The more supports, the more weight. If there are no supports a typical rod can hold 20-30 lbs.
As such any joint can not withstand much weight. It is the support of strong muscles, which make the joint to withstand much higher weight.
The is dual sided and can hold 10 fixed barbells or fixed curl bars. It can support 420 lbs of weight.
2 tonnes
This cart can support a maximum weight of 100 pounds.
That depends on whether or not the shape displaces sufficient water to support the weight of the aluminum.
