What force crushed the can and why?
When the inverted can is placed in cold water, the steam condenses, leaving the can mostly empty, and thus with a very low pressure inside of it. The difference between the low pressure inside and the atmospheric pressure outside exerts an inward force on the walls of the can, causing it to implode.
How many pounds of force do you need to crush a soda can?
According to the research studies, 1pound-2pound force is necessary to open the mouth of the soda can whereas to crush it completely, nearly 50 pounds of force is necessary.
How much force to crush a can?
An actual testing of the beverage can crusher of the present invention, 50 pounds was the maximum force input required to fully crush a seamed steel beverage can whereas the force required to crush all aluminum beverage cans ranged from 5 pounds to 20 pounds.
Why do cans crush in cold water?
When the can is placed in cold water upside down, the hot gas water molecules are cooled very rapidly. This decreases the pressure inside the can. Since the air pressure outside the can is stronger than that inside the can, it causes the can to collapse.
How much force is required to crush an empty aluminum can?
An all aluminum can will support 210 pounds before collapsing, a one-piece tin plated steel can can support 335 pounds before collapsing and a seamed steel can will support 645 pounds before collapsing.
How much weight does it take to crush an aluminum can?
Typically it takes between 100 and 170 pounds to crush an empty soda can. It varies depending on the can construction thickness and individual can flaws. A full soda can can support vastly more .
Why you should crush cans?
That said, if your city or town uses a multi-stream or dual-stream recycling method, crushing cans is beneficial when you recycle cans. Multi-stream means that you separate your recyclables. And since all the cans go together, they can’t contaminate other products.
Why are we not crushed by air pressure?
Air does not crush you down. Fortunately, there is typically just as much pressure inside your body pressing outward as there is air pressure outside your body pushing inward. They typically cancel out, meaning that there is no overall force on you and you don’t get crushed.
How much weight can an aluminum can hold?
Modern aluminum cans are less than a tenth of a millimeter thick, yet hold liquid at up to 90 pounds per square inch (about six times regular atmospheric pressure).
How much force do you need to crush a soda can?
A square inch of a soda can bears 80-90 pounds of force from outside. One atmosphere pressure force is equals to 720lbs or 3200newtons. So, in order to crush a soda can, you need to give nearly 50 pounds of force.
Is there a way to crush a can?
Kudos to NASA and the can company. Note: If you ‘cheat’ and pre-buckle the side of the can with your fingers while pressing down you can crush it much, much more easily.
What is the amount of the force I need to crush an object?
It depends on how are you going to crush it. First know how are you going to crush it. Then find out the crushing stress (which can be tensile stress or any) needed to yield/fracture it. Then multiply by the normal area of crushing of the material. That is the amount of force needed.
What causes a one gallon can to crush?
The resulting large discrepancy between the outside and inside air pressure leads to a large net inward force on the can, ending with its rapid crushing. The one gallon can operates similarly, but its capping and the fact that it is not plunged into cold water results in a slower condensation of the moisture inside the can.
