It depends completely on how you use it. For any given simple machine, you can easily calculate the efficiency ratio, which is applied force/resultant force. Your question has no general answer -- for example, a lever has a vastly different efficiency ratio depending on where you place the fulcrum. The best simple machine in any given situation depends on that situation. There's really no better answer than that. You probably don't want to set up a pully system to get a fridge onto a truck, but you would want one to get a pipe to the top of a skyscraper. One thing to keep in mind is that levers and inclined planes are generally easier to set up and use than other simple machines.

What simple machine can lift a heavy load?
A lever
What kind of simple machine is a marshmallow catapult?
A marshmallow catapult is a type of lever, which is a simple machine that helps to lift or move objects with less force. The lever in the catapult allows for the marshmallow to be launched by applying a force on one end.
Which simple machine does the wheelbarrow use to lift a load?

What simple machine does a wheelbarrow use to lift a load?
A wheelbarrow uses a lever as a simple machine to lift a load. The handle of the wheelbarrow acts as the lever, allowing the user to exert a force to lift the load placed in the container.
What is a simple machine that changes the direction of force to lift an object?
A pulley is a simple machine that changes the direction of force to lift an object. By looping a rope over a pulley, you can pull down to lift the object up.
How do simple machines help us?
Simple machine help us do work like lifting heavy things that we cant lift. This was done by an 8th grader at berea middle school.
What simple machine is made out of two inclined planes put together?
A wedge is a simple machine made out of two inclined planes put together. It is used to split things apart or lift heavy objects when pushed under them.
What are two things a simple machine can do?
A lever can lift objects and a wedge can hold a door open
What a wegde?
A wedge is a simple machine with a sloping surface that helps separate objects, lift heavy objects, or hold things in place. It works by converting a downward force into a horizontal force. Examples of wedges include knives, axes, and doorstops.
What type of simple machine is a ski lift?
A ski lift is a type of simple machine known as a pulley system. It utilizes wheels and ropes to lift skiers up a hill, reducing the amount of force required to do so.
