Ancient civilizations used natural materials like fibers or ropes made from plants like hemp or flax to construct ropes. These ropes were weaved together to create thicker, stronger ropes capable of lifting heavy loads. Pulleys were made by carving wooden or stone wheels with a groove to guide the rope, allowing for easier lifting of heavy stones by decreasing friction and allowing for a mechanical advantage.

What is made with a wheel that has a rope running over it?
A pulley is made with a wheel that has a rope running over it. Pulleys are used to lift or lower loads by pulling on the rope, providing a mechanical advantage to make tasks easier to accomplish.
How can pulleys be used to reduce the force in lifting up an object?
They convert distance into force. So putting a pulley on a load would result in you having to haul up twice as much rope, but lifting about half of the weight of the load. Multiple pulleys increase rope length and further decrease force required to move the load.
What machine allows you to lift things by pulling down on a rope?
A pulley system allows you to lift things by pulling down on a rope. By looping the rope through a pulley wheel, you can change the direction of the force needed to lift the object, making it easier to lift heavy loads. The more pulleys you add to the system, the more the mechanical advantage and the easier it becomes to lift the object.
What are some pulleys?
Some examples of pulleys include clothesline pulleys, flagpole pulleys, and elevator pulleys. Pulleys are simple machines that consist of a wheel with a groove around its circumference and a rope or belt that moves around the groove to lift or lower objects.
How do pulley systems work?
Pulley systems work by distributing the weight of an object across multiple ropes and pulleys, making it easier to lift heavy loads. The more pulleys in the system, the less force is required to lift the object. As you pull down on one end of the rope, the weight is distributed evenly across the pulleys, reducing the effort needed to lift the object.

How did they get the top stone on top of the upright stones at Stonehenge?
They used a series of pulleys and rope,and a lot of man power!

How does a pulley hoist system work to lift heavy objects?
A pulley hoist system works by using multiple pulleys to distribute the weight of a heavy object, making it easier to lift. As you pull on the rope attached to the pulleys, the force is spread out across the pulleys, reducing the amount of force needed to lift the object. This mechanical advantage allows you to lift heavier objects with less effort.

How does pulleys work?
Pulleys can multiply the force you apply. Example: I pull down on a pulley with TWO Pulleys THREE supporting Strands and the force is Multiplied by a factor of TWO, but you have to pull TWICE the length of Rope as the Distance the Object is Raised. Therefore you can LIFT more WEIGHT than you normally could.The relationship of Supporting Strands to the Force Multiplier is:(the number of Supporting Strands) - 1So a Pulley system with 5 Supporting Strands with Multiply YOUR input Force by 4 times. This type of System is referred to as "Block and Tackle".

How can the tension rope pulley be used to efficiently lift heavy objects?
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.
What is the method to find the tension in rope a in a system of pulleys?
To find the tension in rope a in a system of pulleys, you can use the formula T W/(2n), where T is the tension in rope a, W is the weight being lifted, and n is the number of pulleys the rope is passing through.
How does a pulley machine work?
A pulley machine works by using a system of pulleys and ropes or cables to lift and move heavy objects. When force is applied to one end of the rope, it creates tension that is distributed across multiple pulleys, allowing the weight to be lifted with less effort. The more pulleys used in the system, the easier it is to lift heavy loads.
