A lever at a mechanical disadvantage exerts a smaller force on the output arm than is exerted on the input arm; if you push with 10N on a lever with a disadvantage of 2, the other arm only exerts a 5N force.
However, a lever with a mechanical disadvantage exerts the smaller force over a greater distance.
Trebuchets are one example of a mechanically disadvantaged lever: the fairly small projectile doesn't need a huge force to propel it, and the greater distance afforded by the lever allows it to travel at great speed.

A lever is used to lift a load weighing 200N The force needed was 600N What is the mechanical advantage of this first class lever?
3 x 200 N = 600 N.
What does disadvantage mean in science?
It means it sucks
To increase the mechanical advantage of a lever you should?
Easy. The longer the lever is (or the further out you hold it) the more torque you will be able to apply (T = F x r). Also, by pulling the lever perpendicular to it's axis of rotation, no energy will be wasted as it would if you were pulling it to one side or the other against or away from the pivot.
Is it true a simple machine is one that always gives a mechanical advantage of 2?
No. A simple machine such as a lever could quite easily give a mechanical advantage of 10, 100 or more, or could even be less than 1.
What does the M stands for in the abbreviation AMA?
Depending on the context , it might mean " medical". Mechanical = Actual Mechanical Advantage
What is a disadvantage of a lever?
If you wish to multiply force and you are at the right end of the lever the only disadvantage would be the size.
What is the Mechanical Advantage of levers?
The mechanical advantage of the lever is that smaller persons can move heavier objects. The lever can be placed under the object and the person can then push down on the lever.
How do you increase the mechanical advantage of a lever?
The mechanical advantage of a lever can be increased by moving the fulcrum towards the load and away from the power end.
What are the disadvantage of a lever?
disadvantage of first class the fulcrum lies on more effort or more force.
Which type of lever always increases mechanical advantage?
second class lever
What is the number of times the multiplies force called?
Mechanical advantage or is it mechanical disadvantage or mechanical ability by ducky
What are some mechanical devices that begin with the letter L?
A lever is a mechanical device.
What is an example of a mechanical advantage?
Crowbar (lever) .
What is the number of times the machine multiplies force called?
Mechanical advantage or is it mechanical disadvantage or mechanical ability by ducky
What does it mean when the IMA is less than 1.0?
If an IMA (ideal mechanical advantage) is less than one, that means the lever the force is applied to is shorter than the lever lifting the load.
What is the mechanical advantage of a lever?
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
Why are some machines built with mechanical disadvantage?
For flexibility or movement. For example most of our bodies joints have a mechanical disadvantage for the simple reason we gain range of motion and flexibility.
