Which pulley setup would decrease the amount of effort force needed to life an objected?

A pulley system with more movable pulleys will decrease the effort force needed to lift an object. This is because the load is distributed among multiple strands of the rope, reducing the force required to lift the object.


How will the amount of pulleys affect the amount of force?

Using more pulleys in a system can decrease the amount of force needed to lift an object. Each additional pulley reduces the amount of force required by distributing the load across multiple ropes, decreasing the overall effort needed.


What type of pully can multiply effort force?

Actually, pulleys cannot multiply effort force. It can only change the direction of the effort force.


What simple machine reduces the amount of effort needed to lift a heavy object?

Lever Hoist


How does moving fulcrum on a lever change the amount of force needed to move an object?

how does moving a fulcrum on a lever change the amount of force needed to move an object


On a lever how can you reduce the amount of effort needed to lift a heavy object?

You can reduce the amount of effort needed by moving the object closer to the fulcrum which acts as the pivot point of the lever. This increases the mechanical advantage of the lever, requiring less force to lift the object. Additionally, using a longer lever arm will also reduce the amount of effort needed.


Does a pulley make work easier by changing the direction of force?

Yes, a pulley make work easier by changing the direction of the force needed to lift an object. It allows you to pull downward on the rope instead of lifting upwards, which can reduce the amount of effort required to lift the object.


In a movable pulley system where does the other effort come from?

In a movable pulley system, the other effort comes from the weight of the object being lifted. The movable pulley reduces the amount of force needed to lift the object by distributing the load between the pulling force and the weight of the object. As a result, the effort needed to lift the object is divided between the pulling force and the weight of the object itself.


What is the relationship between the effort and the weight of an object being lifted over a simple pulley?

the effort needed to lift an object is about the same as the weight of an object:)


What does a block and tackle do?

It decreases the effort needed to lift an object.


How does a pulley decrease work?

A pulley decreases the amount of work needed to lift an object by distributing the force required over multiple ropes and pulleys. This reduces the amount of force needed by the person pulling the rope, making it easier to lift the object.


What is the advantage of using an inclined plane to lift an object is that it reduces the amount of?

The advantage of using an inclined plane to lift an object is that it reduces the amount of force needed to lift the object. By increasing the distance over which the force is applied, an inclined plane decreases the amount of effort required to lift an object to a certain height.
