A simple pulley is a rope (or chain or belt) with one wheel this may be a class 1 or class 2 pulley.
- For a class 1 pulley, the pulley stationary and the force applied to the rope is in the opposite direction as the movement of the object.
- For a class 2 pulley, the pulley is attached to the moving object and the force applied to the rope is in the same direction as the motion of the object.
A compound pulley, consisting of an arrangement of more than one simple pulley, provides many other possibilities with the direction of force either the same direction or the opposite direction of the motion of the object being moved.
What else can I help you with?
What force is required to lift something on a pulley?
The force required to lift an object using a pulley system depends on the weight of the object being lifted. The force needed is equal to the weight of the object being lifted plus the force required to overcome any friction in the pulley system. The mechanical advantage provided by the pulley system can help reduce the amount of force needed to lift the object.
What type of friction does a pulley overcome?
A pulley overcomes static friction, which is the friction between the surface of the pulley and the rope or belt moving over it. This allows the pulley to rotate smoothly and lift objects with less force required.
Where is force applied in a pulley?
Force is applied to a pulley at the point where the rope or cable passes over the wheel or sheave. This force is used to lift or move objects by leveraging the mechanical advantage of the pulley system.
In a machine the effort force you apply is used to overcome a what force?
In a machine, the effort force you apply is used to overcome a resistance force. The resistance force is the force that the machine acts against in order to perform work.
Which pulley is used to changed the direction of the force?
A changing the direction of force is generally achieved using a fixed pulley or a movable pulley, depending on the specific setup. Both types can redirect the force being applied to a different direction without changing the amount of force.

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 changing the direction of force is generally achieved using a fixed pulley or a movable pulley, depending on the specific setup. Both types can redirect the force being applied to a different direction without changing the amount of force.
Does the force used to lift an object using a single pulley alter depending on the size of the pulley?
no
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
What is used with a pully to change the direction of a force?
A pulley is typically used with a rope or cable to change the direction of a force. The rope or cable wraps around the pulley, allowing the force to be redirected in a different path.
If a person wants to raise the 100 N weight how much downward force must he exert on the rope?
If you have a single pulley, then you would need to exert 100N + an amount to overcome friction in your pulley.If you have 2 pulleys, rope connected to a beam at top, descends through pulley on item lifted, and back up through pulley at the top and then down to where you are pulling. Then the force is split in half and you would exert 50N + an amount to overcome friction.If you connect a rope to the item, up through a double pulley, down through a pulley on the item, and back up through the double pulley again and down to the person who is pulling. Then you divide the force into thirds, and the force is 33.3N + an amount to overcome friction.Essentially count the upward pulling ropes and divide by that number. A rope simply looping over a pulley that you're hanging onto the other end of only counts as once, and would be no different from you pulling up directly on the object, or on a pulley connected to the object.
