Traction advantage , moving one place to another location
Nomads are people who live in sort of a tribe. They don't live in one place, they keep moving with their tribe.
paper is fixed & only pens are moving horizontaly
Assuming they are all part of the torque-multiplier, and the hauling end is moving parallel with the load end, the advantage is 4:1.
The mechanical advantage of a lever can be increased by moving the fulcrum towards the load and away from the power end.
During the Paleolithic period, human dwellings consisted of temporary shelters such as caves, rock shelters, and simple structures made from materials like sticks, leaves, and animal hides. These early humans were mainly nomadic, moving from place to place in search of food and resources.
The mechanical advantage of a pulley system depends on the number of ropes supporting the moving block or load. More ropes mean a higher mechanical advantage.
The moving part of a lever is the rigid bar or beam that pivots around a fulcrum. This moving part exerts a mechanical advantage by magnifying the force applied to it.
The position of the fulcrum affects the mechanical advantage by changing the ratio of the input force to the output force. Moving the fulcrum closer to the load increases the mechanical advantage, making it easier to lift the load. Conversely, moving the fulcrum closer to the effort force decreases the mechanical advantage, requiring more effort to lift the load.
It can mate with the closest organism no matter what sex.
Changing the fulcrum position of a lever can affect the mechanical advantage by changing the ratio of the lever arms on either side of the fulcrum. Moving the fulcrum closer to the load will increase the mechanical advantage, making it easier to lift the load. Conversely, moving the fulcrum closer to the effort force will decrease the mechanical advantage, requiring more effort to lift the load.
