Name someapplications of pressure

Some handbags has a thin strap. The thin strap contact with the shoulder produced high pressure caused our shoulder felt pain. The smaller the surface area of the handbag strap, the higher the pressure produced. Use the handkerchief that is used to increase the surface area of the thin strap. The larger the surface area of the handbag strap, the lower the pressure produced.
Lets take a situation of fixing a broken table using the nail. First, we take a nail whose tip is blunt. When a force is applied to hit the nail, the nail does not buried into the table. This is because by the large area of the nail tip in contact with the table produce low pressure. The larger the tip area of the nail, the more time taken to completely immerse the nail to the table. Next, we take a nail whose tip is sharp. The small area of the nail tip in contact with the table produce high pressure and make hitting the nail into the table become easier. The smaller the tip area of the nail, the less time taken to completely immerse the nail to the table.
Massage is one type of application of pressure. By doing this it reflexes the feet, hands, ears and their referral areas within zone related areas, which correspond to every part, gland and organ of the body. This is because while giving pressure it pushes the nerves and we don’t get any pain later.
When we pull the plunger out on a syringe it causes the volume within the chamber to increase. As we know, this causes the pressure do the opposite, which creates a vacuum attempting to re-pressurize back to atmospheric levels. Since the only fluid available on the other side of the needle tends to be a liquid such as blood, which gets sucked into the chamber, reducing the volume and increasing the pressure back to where it wants to be.
We know that before we spray a can of paint we are suppose to shake it up for a while, listening as a ball bearing rattles around inside. The can is sealed, preventing this gas from boiling and turning into a gaseous state. That is, until we push down the nozzle. The moment the nozzle goes down, and the seal is released, there is now an escape route. The propellant instantly boils and expands into a gas and pushes down on the product trying to escape the high pressure, and expand it’s volume the atmosphere where there is less pressure. This forces the product to shoot out from the nozzle, and we have a coat of paint.
Typically we will take a bottle of soda, slowly turning the cap allowing the air to gradually escape before completely removing the lid. We do this because we’ve learned over time that popping it open too fast causes it to fizz up and spill all over us and everything around us.
