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.
A surface that re-directs force using a rope is called?
pulley
The force applied when using a simple machine.?
The force applied when using a simple machine is typically referred to as input force. The input force is the force that is used to operate the machine and is usually applied through a lever, pulley, or other mechanism to overcome resistance (output force) and perform work. The ratio of the output force to the input force is known as the mechanical advantage of the machine.
Does the force used to lift an object using a single pulley alter depending on the size of the pulley?
no
What is the advantage of using a movable pulley?
A movable pulley reduces the amount of force needed to lift an object because it changes the direction of the force. When using a movable pulley, the load is shared between the pulley and the user, making it easier to lift heavy objects.
What is a surface that redirects force using a rope?
A pulley is a surface that redirects force using a rope. By changing the direction of the force applied to the rope, pulleys can help in lifting heavy objects or changing the direction of a force.
Do you use more force using 1 pulley to pull an object or 1 or more pulleys?
More force is exerted with one pulley.
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.
A surface that re-directs force using a rope?
Is a pulley
How are a fixed pulley and a movablepulleydiffrent?
Using a movable pulley is known as using it to 'advantage'. The line going to the movable pulley contributes towards the force acting on the load. A line going to a fixed pulley, only serves to change the direction of the force.
How much effort is needed to lift a 75 N weight using the pulley system?
If you are talking about a simple pulley with the pulley attached and load rope attached to the object then you will need a little more than 75N of force. Lifting an object (at a constant velocity) requires a force equal but opposite the weight of the object. With any simple machine you will need to do more work to overcome friction. If you were to use a single pulley with the pulley attached to the object then you will need a little more than 37.5 N. If you were to use a multiple pulley system then you would need to know the mechanical advantage of the pulley system.
What pulley system will lift the weight using the least amount of effort force?
A compound pulley system using multiple pulleys will require the least amount of effort force to lift a weight. The mechanical advantage of a compound pulley system increases with the number of pulleys, reducing the amount of force needed to lift the weight.
