How do you design a machine to lift 2kg of mass with only 1kg of effort force?

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?
It makes it easier for the effort force [such as your hand] to lift the resistance force [such as a heavy object].
What does hefted mean?
Weight; heaviness or bulk. Also, to lift something.
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.
Keeping the location of the effort constant Will the effort increase if the load is moved farther away from the fulcrum?
The magnitude of the effort is controlled by you, not by the distance of the load from the fulcrum. Moving the load farther away from the fulcrum has no effect on the effort. But if you want to leave the effort where it is and still lift the load with the lever, then you're going to have to increase the effort.
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 force a lever uses to lift a load is?
effort force
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.
What simple machine reduces the amount of effort needed to lift a heavy object?
Lever Hoist
What pulley system will lift the weight using the least amount of effort force?
balls. =))
How do machines make it easier to lift things?
The simplest machine for lifting is a class one lever. It takes human effort and multiplies it. All other forms of lifting equipment replaces human effort with mechanical force generated by an engine of some form.

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
What is a simple machine that changes the direction of force to lift an object?
An inclined plane (ramp).
How much effort force would you use to lift a kg weight with a fixed pulley system?
a lot
How much effort force would you use to lift a 300 kg weight with a fixed pulley?
a lot
How many pounds of effort force does a lever have if it has an effort arm of fifteen units long and a resistance arm of 10 units and can lift a 3-pound weight?
It would require (3 X 10)/15 = 2 lb to lift the 3 lb weight. Actually, something a little greater than that. 2 lb is the force to balance it. (Obviously, the lever "has" no force. It requires the force to lift the weight.)
