First of all, "1 kg" is a mass, not a force. But we'll let that pass for right now,
and move on to answering the question. Twice.
1). Set up a miniature see-saw. Place the pivot 1/3 of the way between the ends,
so that the one end of the see-saw is double the length of the other end. Set the
load on the short end, and push down on the long end. The force it takes to lift
the load will be 1/2 the weight of the load.
2). Fasten one end of a rope to the ceiling. Pass the free end of the rope through
a pulley, and hold the free end up so the pulley doesn't fall off. Hang the load from
the pulley, and slowly lift the free end of the rope. The force on the free end that
you need to lift the load will be 1/2 the weight of the load.

What are the functions of a first class lever?
A first-class lever is a simple machine consisting of a rigid rod (lever) that pivots around a fixed point (fulcrum). It is used to increase force, gain speed or distance, or change the direction of a force. Common examples include scissors, seesaws, and crowbars.
What machine can get a large rock out of the ground?
A large lever can move a boulder by increasing your lifting power. With the fulcrum closer to the boulder and your force exerted farther away, you can lift it. The lever changes a small force exerted over a long path into a large force exerted over a small path.
How does a movable pulley make work easier?
A fixed pulley is the only pulley that when used individually, uses more effort than the load to lift the load from the ground. The fixed pulley when attached to an unmovable object e.g. a ceiling or wall, acts as a first class lever with the fulcrum being located at the axis but with a minor change, the bar becomes a rope. The advantage of the fixed pulley is that you do not have to pull or push the pulley up and down. The disadvantage is that you have to apply more effort than the load
Why does the input force have to be greater than the force need to lift the bale?
If the force is not greater than the weight of the bale, the bale will not move.
What is the length from the fulcrum to the load?
That is the distance between the load and the fulcrum. The load may be on the far side, or the near side of the fulcrum. One often overlooked fact, is that as the distance from load to fulcrum increases, the load on the fulcrum decreases.
In a machine what force does the effort force try to overcome?
In a machine, the effort force tries to overcome the resistance force. The effort force is applied to the machine in order to move or lift the resistance force, which is the force that opposes the motion or lifting action. The difference between the effort force and the resistance force determines the mechanical advantage of the machine.
In a machine the effort force you apply is used to overcome a?
In a machine, the effort force you apply is used to overcome a resistance force, such as the force of friction, gravity, or inertia. The goal of the machine is to make it easier for you to move or lift objects by increasing efficiency or changing the direction of the force applied.
The ratio of resistance force to effort force.?
The mechanical advantage is the ratio of resistance force to effort force in a simple machine. It indicates how much the machine amplifies force. A mechanical advantage greater than 1 means the machine multiplies force, making it easier to lift or move an object.
How does the length of the effort arm for a lever affect the amount of required effort force?
The longer the effort arm of a lever, the less effort force is needed to lift a load. This is because a longer effort arm increases the leverage, allowing a small effort force to lift a greater load. Conversely, a shorter effort arm requires a greater effort force to lift the same load.
What is effort load?
Effort load is how much force it takes to lift and object. You can measure effort force with a spring scale.
A movable pulley reduces the amount of effort needed to lift a lode by making what change?
A movable pulley reduces the effort needed to lift a load by changing the direction of the force required to lift the load. By pulling down on one end of the pulley system, the load is lifted up with less force needed due to the mechanical advantage gained from the pulley's design.
How would you describe the effort force?
Effort force is a force used to move an object over distance.Which ball will bounce higher lacrosse ball or tennis ball?Read more: Which_ball_will_bounce_higher_lacrosse_ball_or_tennis_ball
When you hoist the flag on heroes day you use a simple machine called?
a pulley. Pulleys help to lift heavy objects with less effort by distributing the force needed to lift the flag.
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 much effort force would you use to lift 300kg with a fixed pulley?
With a fixed pulley, the effort force would be equal to the weight being lifted (300kg) in this case. So, to lift 300kg using a fixed pulley, you would need to apply an effort force of 300 kg-force.
Which arrangement would require the least amount of effort force to lift the load?
A pulley system with a mechanical advantage of 4 would require the least amount of effort force to lift a load. This means that for every 4 units of load force, only 1 unit of effort force is needed.
What is the effort force to lift a 10kg load?
The effort force required to lift a 10kg load would be equal to the weight of the load, which is 10kg multiplied by the gravitational acceleration, which is approximately 9.81 m/s^2. So, the effort force would be approximately 98.1 Newtons.
