It is easier to lift a load with a lever. You exert a large force over a small distance on the load end by exerting only a small force over a greater distance at the effort end. The following equation, and example, may help you visualize it.
load arm X load force = effort arm X effort force
Now imagine that you have a one kilogram rock, and a one gram feather. If you place the the rock 1 cm to the left of the fulcrum, and the feather 1 meter to the right of the fulcrum, the two will be balanced. This is because the feather is 1000 times farther from the fulcrum than the rock. So, even though the rock is 1000 times heavier than the feather, the feather has a mechanical advantage, which balances it out on the fulcrum.

How can you make it easier to lift the load when the load is at a constant position on the lever arm?
when the load is at a constant position on the lever arm, how can you make it easier to life the load?
What the solid bar that rests on a fulcrum?
The lever? There are probably other names for it, but i was always taught the fulcrum, lever, and load. Load closer to fulcrum, easier to lift load. (longer lever= mechanical advantage) This would fall under simple machines in science class.
What is the mechancial advantage of lever that can lift a 100 N load with an input force of 20 N?
The mechanical advantage of a lever is that it can lift a 100N load with an input of 20N is calculated as is 5. In this case, the effort is divided by the load.
What force a lever uses to lift a load is?
effort force
How does lever simplify work explain?
A lever works by reducing the amount of force needed to move an object or lift a load. A lever does this by increasing the distance through which the force acts . Lever neither increases or decreases the amount of total effort necessary . Instead , they make the work easier and simpler.
When the load is at a constant position on the lever arm how can you make it easier to lift the load?

Why it is easier to lift the load in a wheelbarrow when the load is shifted towards the wheel?
If become easier to lift a load in a wheelbarrow when the load is towards wheel why
What simple machine can lift a heavy load?
A lever

What force a lever uses to lift a load is?
effort force
How efficient is a lever?
That depends where the fulcrum is. The closer the fulcrum is to the load (one-class lever), the easier.
Where should the fulcrum effort be placed to easily lift the load resistance?
As close to the load as possible. Note that the closer to the load the fulcrum is placed, the shorter the lift that can be effectuated by the use of the lever.
Small effort to lift the load of 1st class lever?
This will occur if the fulcrum is closer to the load than the effort
