Water helps lift an objects via the buoyancy force. The buoyancy force is equal to the weight of water displaced by the volume of the submerged object. If this buoyancy force is equal to the weight of the object, the object will float in that position. If the object is completely submerged and the resulting buoyancy force is less than the weight of the object, it will continue to sink.
A two-dimensional doublet is a theoretical representation of fluid flow in which the fluid is assumed to circulate around a line vortex. It is a simplification used in fluid dynamics to model the behavior of flow around objects like airfoils or ships, where the flow can be represented by a combination of uniform flow and doublet flow to approximate the effects of lift and drag.
In fluid mechanics, "head" refers to the potential energy per unit weight of fluid due to its elevation above a reference point. It is often used in pump systems to describe the energy that the pump imparts to the fluid to overcome resistance and lift the fluid to a certain height. Head is typically measured in units of length, such as meters or feet.
Gas lift is a method used in increasing the production of oil from a well by injecting gas after the inherent pressure in the well must have dropped after a fairly long time(this is a function of the well dynamics ). Gas gotten from the well along with the oil is removed through separators and compressed before re-injection into the tubing casing annulus. The gas enters into the tubing through gas mandrels on the tubing strings and through a gas valve. The gas aerates the fluid and makes it less dense thereby reducing its viscosity and this makes the formation pressure push out more fluid.
Tongs are used in a lab to handle hot objects, such as beakers or flasks, without having to physically touch them. They provide a safe way to lift and move items without the risk of burns.
Heavy water is sometimes used in fiber optic cables as a coiling fluid, also known as a secondary coating material. It helps to reduce stress on the optical fibers within the cable and provides protection. By using heavy water, the cables can withstand bending and stretching without breaking.
because we can't lift it with our hand
The tension rope pulley can be used to efficiently lift heavy objects by distributing the weight of the object across multiple pulleys, reducing the amount of force needed to lift it. This allows for a mechanical advantage, making it easier to lift heavy objects with less effort.
A lever is used to lift heavy objects because it magnifies the input force applied to it. By using a lever, a person can apply a smaller force over a longer distance to lift a heavier load over a shorter distance. This principle allows for the efficient lifting of heavy objects with less effort.
Yes, a pulley is a simple machine that is commonly used to lift heavy objects by reducing the amount of force required to lift them. It works by changing the direction of the force applied and distributing it evenly among multiple ropes or cables, making it easier to lift heavy loads.
Biceps function to lift your forearm up to touch your shoulder. They are often used in cooperation with the muscles in your back to lift heavy objects.
A lever is often used to lift or move heavy objects with less effort. It can also be used to apply force at a specific point to do tasks like prying, cutting, or holding objects in place. Examples include using a crowbar to lift a heavy object, using scissors to cut paper, or using a fishing rod to lift a fish out of the water.

The pulley was discovered to lift objects that would otherwise be too heavy to lift. Much in the way a crane is used to lift cargo onto ships.
No, pulleys can be used to lift heavy or light objects. The mechanical advantage of pulleys allows for an easier lifting process regardless of the weight being lifted.
A pulley can be used to lift heavy objects, lower objects, or to change the direction of a force. It is commonly used in various applications such as construction, manufacturing, and transportation to make tasks easier and more efficient.
A pulley system can be used to lift heavy objects efficiently by distributing the weight across multiple ropes and pulleys, reducing the amount of force needed to lift the object. This allows for easier lifting of heavy loads by taking advantage of mechanical advantage.
A screw jack is an object that is used to lift the car and other heavy objects off the ground.
