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 else can I help you with?
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.
How do you calculate effort force in pulley system?
To calculate the effort force in a pulley system, start by counting the number of supporting ropes that are directly attached to the movable pulley. Divide the total weight being lifted by this number to find the effort force needed to lift the weight. This assumes an ideal pulley system with no friction or other resistive forces.
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.
How much effort force would you use to lift a 300kg weight with a movable pulley system?
With a movable pulley system, you would need to exert an effort force equal to half the weight being lifted. In this case, to lift a 300kg weight, you would need to apply an effort force of 150kg. This is because movable pulleys provide a mechanical advantage of 2, reducing the amount of effort force needed.
Why the value of single movable pulley is 2?
A single movable pulley has a mechanical advantage of 2 because it reduces the effort needed to lift an object by half. This is due to the pulley system allowing the weight to be distributed between the weight being lifted and the tension in the supporting rope.
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.

This is because movable pulleys provide a mechanical advantage of 2, reducing the amount of effort force needed.
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:)
How are the double pulley systems different?
Double pulley systems are different from the one pulley system because the weight is now attacked to a pulley instead of an anchor. Another pulley is used to take some of the weight. A two pulley system only requires half the effort as a single pulley system.
Why the value of single movable pulley is 2?
A single movable pulley has a mechanical advantage of 2 because it reduces the effort needed to lift an object by half. This is due to the pulley system allowing the weight to be distributed between the weight being lifted and the tension in the supporting rope.
How much effort force would you use to lift a 300 kg weight with a movable pulley system?
In a movable pulley system, the effort force required is half of the weight being lifted. So, to lift a 300 kg weight, you would need to apply an effort force equal to 150 kg.
How much effort force would you use to lift a kg weight with a fixed pulley system?
a lot
Working principle of pulley system?
A pulley system works on the principle of reducing the force needed to lift a load by distributing the weight over multiple ropes and pulleys. As you add more pulleys to the system, the force required to lift the load decreases as the weight is distributed more evenly. This allows you to lift heavier objects with less effort.
How much effort force would you use to lift a 300-kg weight with a moveable pulley system?
150
How do you calculate the distance the rope needs to be pulled to lift the load?
The distance the rope needs to be pulled to lift the load can be calculated using the formula: Distance = (Load weight * Pulley system efficiency) / Effort force applied Efficiency of the pulley system depends on the number of ropes supporting the load. The effort force applied is the force needed to lift the load.
