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 100 pounds against gravity, you would need to apply a force of 100 pounds. This accounts for overcoming the force of gravity pulling the object downward. If the object is being lifted vertically at a constant speed, the force required would be equal to the weight of the object.
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.
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.
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.
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.

Any one in the Newton family can lift over 50 lbs. The youngest is 12 yrs old.

Using 3 pulleys in a block and tackle system reduces the force required to lift an object by one-third. Therefore, to lift 100 lbs with 3 pulleys, you would need to apply approximately 33.33 lbs of force.
Assuming the pivot is positioned at a 90-degree angle and ignoring friction, it would take a 100-pound force applied at the end of a 1-foot-long lever arm to lift 100 pounds. This is based on the principle of torque, where the force applied multiplied by the distance from the pivot point determines the weight that can be lifted.
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 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.
about 100 pounds
