A single wheel pulley means that the rope you hold has one attachment to the load so the force is the same as the load, just in a different direction. So lifting something means you could actually apply the whole of your weight to the rope, rather than just the strength of your muscles. (Multiple pulley wheels mean that the same rope tension is applied to the load several times, so the force you apply to the rope is applied to the load several times.)

What is a system of pulleys designed to multiply the effort force called?
moveable pulley
How much does a block and tackle pulley system multiply the effort force?
4 (:
What type of pulley would increase the output force?
A pulley system that has multiple pulleys in line with each one having its output drive the next will increase the force. This would be called a tackle pulley.
What is true of a real machine that enables a person to move a heavy object with little applied force?
I'd go with simple machines. Specifically, probably a pulley (or pulley system).
If the input force on a pulley is 3 N and the output force is also 3 N what is its mechanical advantages?
1
A pulley system can?
Change the direction of force and multiply the force.
How is a pulley and a lever alike?
A pulley and a lever are both simple machines that help to make work easier by changing the direction or magnitude of a force. They both utilize the principle of mechanical advantage to multiply force or distance.
Does a fixed pulley multiply input force?
no it can't.
Does a moveable pulley multiply the input force?
Yes. The IMA of a movable pulley is 2.
How does a pulley change directions of force?
A pulley changes the direction of force by redirecting the force applied to it. When force is applied to one side of the pulley, the pulley redirects that force to the other side, allowing you to change the direction of the force being applied. This makes it easier to lift or move objects in different directions.
What kind of pulley can increase the effort force?
A movable pulley can increase the effort force. By attaching the pulley to the object being lifted and pulling downward, the force required to lift the object is reduced, making it easier to lift heavier loads.
How do you do a pulley system?
A Pulley is basically a kind of lever that can be used to change the direction of a force. Properly used, a pulley or system of pulleys can multiply forces

A system of pulleys designed to multiply the effort force is called a what?

How does a fixed pulley make work easier?
A fixed pulley does not make the force applied easier, it changes the direction of this force. For example, instead of bending over and lifting and object, a fixed pulley lets you lift it by pulling down on a rope.
How do you describe a pulley system?
A Pulley is basically a kind of lever that can be used to change the direction of a force. Properly used, a pulley or system of pulleys can multiply forces
