To lift 200 pounds of weight, you would need to apply a force equal to the weight being lifted, which in this case is 200 pounds. This is because the force needed to lift an object against gravity is equal to its weight.
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.
If the weight is 300 pounds, you will need to apply a force of at least 300 pounds to lift it against the force of gravity. This force is known as the weight of the object.
The force needed to lift a weight of 200N would be 200N. This is because the force needed to lift an object against gravity is equal to the weight of the object itself.
Yes, the position of the fulcrum affects the force required to lift a weight. Placing the fulcrum closer to the load reduces the effort needed to lift the weight. Conversely, placing the fulcrum further from the load increases the force needed to lift the weight.
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.
Yes, the position of the fulcrum affects the force required to lift a weight. Placing the fulcrum closer to the load reduces the effort needed to lift the weight. Conversely, placing the fulcrum further from the load increases the force needed to lift the weight.

To lift a 60 pound rock with a mechanical advantage of 4, you would need to apply 15 pounds of force. This is because the force needed is the weight of the rock divided by the mechanical advantage (60 pounds / 4 = 15 pounds).
A fixed pulley can lift weight with the least amount of force. It changes the direction of the force needed to lift the weight but does not provide any mechanical advantage.
To lift 300 pounds using two pulleys, you would generally need to lift half the weight, assuming the pulleys are set up in a way that provides mechanical advantage (like a block and tackle system). Therefore, you would need approximately 150 pounds of force to lift 300 pounds with two pulleys. However, the exact weight needed can vary based on the efficiency of the pulleys and any friction involved in the system.
A movable pulley reduces the input force needed to lift weights by distributing the weight between two strands of rope. As the pulley moves up, the weight on one side is balanced by the force exerted on the other side, effectively halving the force needed to lift the weight. This mechanical advantage makes it easier to lift heavy objects.
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.
The same force as the weight of the helicopter and its crew and cargo.
