You can use a pulley to pull things up. It is a mechanical structure which helps to pick things up.
A pulley is a simple machine consisting of a grooved wheel and a rope or cable. It is used to change the direction of a force, making it easier to lift or move heavy objects. When you pull on one end of the rope, the object on the other end moves in the opposite direction.
In a movable pulley system, the effort force required would be equal to half the weight being lifted. So to lift a 300 kg weight, you would need to apply an effort force of 150 kg (approximately 1471 Newtons) assuming ideal conditions and neglecting friction and other losses.
A fixed pulley is attached to a surface and only changes the direction of the force applied, while a movable pulley is attached to the object being moved and changes both the direction and the amount of force required to move the object.
You can't carry an object without carrying it. If you mean without touching it you will have to be creative. Use a lever and pully system, roll it with a ramp, use a forklift...
When the pully is not active, it is using potential energy. But when a person or a machine uses the pully, they use force to make Kinetic Energy and to lift the box....but that's what i know so far...but i . :)
You would use a 5 inch sheave.
MIT would be the wheel
A pully is used to lift heavy things you normally would have difficulty lifting with your bare hands.
remove the bolt on the pully or use a pully remover depending on the style of pully and put new one on.
No. String and pully.
a pully was used for lifting heavy things
wrap the belt around the pully to hold pully still
Any non-mechanical weight machine, such as a pully machine would be great for heavy, regular use.
A pully is used to lift thing depending on how big the obJect is

for one movable pulley you would get a mechanical advantage of 2
