The simple machines - a lever for example - are usually designed so that you need less force. In compensation, you need to move the lever for a greater distance. This follows directly from the law of conservation of energy.

Why do levers have a greater mechanical efficiency than other simple machines do?
You can move a large load using a relatively small effort. http://www.deyes.sefton.sch.uk/technology/AS&Alevel/mechanical_systems.htm
When doing work using simple machine's what happens when the effort distance is increased?
the effort is decreased
What would life be without simple machines?
Do you mean technological development? Then the answer is no. All complex machines are made up of simple machines in various combinations. Without the one, you can't have the other. The world would go on, of course, but the technological complexities of its modern civilizations could not exist without simple machines.
What simple machines make up complex machines?
A complex machine is a machine using more than one simple machine for its operation. A bicycle is a complex machine, using a lever for steering (handlebars), wheel and axle, inclined plane (the threads on bolts), and a pulley (chain on sprockets).
Advantages of simple machines?
Simple machines are considered simple because they usually only have one part or need one force to work.
What is essence of using simple machine?
Simple machines lets you trade force for distance, or the other way around. Or they change the direction of a force.
What are the safety precaution in using machines?
the safety precaution in using simple machines is to use it in a safety hand

How long have people been using simple machines?
people have been using it forever
What Compound machine using 6 simple machines?
the six machines are hydrolic ect. etc. and compound is the first?
What is the results of how does a simple machine work?
my results are that simple machines work by using force and some work.
Can simple machines increase force?
What is the ‘cost’ for using a machine to increase force
How does using a simple machine solve problems?
Using simple machines like pulleys, levers, etc. Solve problems because chickens use Pottys
Where is the extra distance put when using a simple machines?
on my homework I put that it increases the force
What is the purpose of using simple machines?
because it helps you do things your too lazy to do yourself.
