The mechanical advantage of the block and pulley you are using, or the engine of the fork lift truck if that is what you are using.
efficiency=mechanical advantage/velocity ratio mechanical advantage=load/effort use this formula, ans:100N
the one with the fulcrum closer to the weight you needed to lift
For humans = Chemical energyFor machines = Mechanical energy.
It depends on the output force and input force and what the levers look like. For example: if you can use a type one lever to lift 500 N with 100N, the adv would be 5. But, if you can only lift the 500N with 250N, then the adv is 2.
Ariel lift is considered a mechanical device. It is used to provide temporary access for people or equipment to inaccessible areas.
TURBINES: generate electricity. use an input to obtain mechanical output. PUMPS: Basically create lift in water. Use mechanical input to create an out put
Two words, mechanical advantage.
The pulley in the mechanical device work together to make the lift move up and down. Counter weights.

In 1420 Filippo Brunelleschi was building the dome of the Doma in Florence, Italy and to get the building materials up to the highest reaches of the dome he invented a mechanical lift. It was not run by electricity, but mule/horse power, yet, it did have gears, pulleys, and wheels so it was mechanical.
Mechanical Advantage lets you use a small amount of force to lift a heavy weight. You can not pick up the corner of a car to change the tire. You can use a jack. Mechanical advantage lets you move your arm down several feet to move the jack up a fraction of an inch. By moving your arms many times, you can lift a heavy car. You can change your tire and not be stuck off in the woods, and have to walk several miles to get someone to help you. I think that is important.
use the lift key to use the lift

Hoist is what you do to haul something up.
