That depends on a variety of circumstances. Mainly:
To calculate the force needed to pull down 100 lbs using a rope, you would need to know the angle at which the force is being applied and any other factors that may affect the force required. In a simplistic scenario with no angle or other factors, you would need to exert at least 100 lbs of force to counteract the weight of the object being pulled down.
The force required to lift 100 pounds is approximately 100 pounds since the force needed to overcome gravity is equal to the weight of the object being lifted. This force, equivalent to the weight of the object, must be greater than or equal to the force of gravity acting on it.
To lift the 100-pound square weight, a force equal to or greater than 100 pounds must be exerted on the rope. This force needs to overcome the weight of the object and any friction or resistance present in the system.
In a Pulley System, the number of "Supporting Strings" is equal to the Force multiplier of the system. That is, if there are 4 supporting strings (plus the string you pull on), and the object being raised weighs 100 pounds, then the effort you supply is only 25 pounds. The Pulley System has a force multiplier of 4 times the input.
If the pulley is fixed (hanging from the ceiling), and the rope passes over it, then 100 lbs of force is required. If the rope is fixed to the ceiling and passes under the pulley (which is fixed to the load), then 50 lbs of force is required.

To pull down 100 lbs using 3 pulleys, the force required would be one-third of the weight being lifted, so 33.33 lbs. This force is distributed across the three pulleys, with each pulley supporting roughly one-third of the load.
The person's weight on Saturn would be different than on Earth because gravitational pull varies depending on the planet. On Saturn, the gravitational pull is weaker than on Earth, so the person would weigh less. The exact weight would depend on Saturn's specific gravitational force.
Well, darling, if the weight being lifted is 100 lbs., you'll need to apply at least 100 lbs. of force to lift it using a simple machine. It's all about good old Newton's third law - for every action, there's an equal and opposite reaction. So, put those muscles to work and give that weight a good lift!
If you have a man submerged up to his neck in corn and you want to know how many pounds of force it will take to lift him out, information about the volume, weight, mass, density would be needed in order to calculate the force needed.
To lift a 100 pound weight, you would need to apply a force that is equal to or greater than 100 pounds. This is due to Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. So, the force applied must be at least 100 pounds to overcome the force of gravity acting on the weight.
In a movable pulley system, only half of the weight needs to be lifted, so the force needed would be 500 N (100 kg * 9.81 m/s^2 / 2). This is because the pulley is reducing the amount of force required by distributing the load between two sections of the rope.
If you have 2 pulleys in a system to lift a 100 lb object, the amount of force required to lift it would be 50 lbs. This is because the weight is distributed evenly between the two pulleys, therefore reducing the force needed to lift the load.
