It has to do with a type of force called torque. When you push down on a lever, the force you push with is multiplied by the length of the lever to produce a torque. If you have a very long lever, then you are multiplying your pushing force by a big number and can produce a big torque. It's an easy way to get a large force with little effort.

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.
How do you calculate a lever's mechanical advantage?
From the design of the lever (on paper), the mechanical advantage is effort arm/load arm which means Distance from pivot to the applied force/distance from pivot to the load The result of that is that the forces will have the reciprocal ratio, and the input force to the lever will be the output force/the Mechanical Advantage .
What is the Ideal Mechanical Advantage of a lever that has a fulcrum in the exact center?
One.
How do you change the mechanical advantage of first class lever?
Move the focal point of the leaver.
What is the mechanical advantage of a machine which multiplies distance?
The mechanical advantage of the machine is"if you give small accelration , it will increase the speed of the engine... It is possible by mechanical
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 is the increase in work done by a lever called?
Mechanical advantage .
What can be increased on a lever increase it's mechanical advantage?
Effort Arm
What is a fulrum?
an aid used to increase or decrease the mechanical advantage of a lever
What is a lever with a mechanical advantage greater than one used to do?
Mechanical advantage refers to the ratio of the force produced by a machine to the force applied to it. A lever with a mechanical advantage greater than one is used to increase distance.
What A lever with mechanical advantage greater than one is used to?
increase distance.
A lever with a mechanical advantage greater than one is used to do what?
A lever with a mechanical advantage greater than one is used to increase distance. A lever is a simple machine connected to ground by a hinge called a fulcrum.
What is the mechanical advantage of a lever?
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
What A lever has a resistance arm of 5 feet and an effort arm of 6 feet What measurement can be changed to increase the mechanical advantage of the lever?
increase the effort arm to 8 feet
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.
What would increase the mechanical advantage of a first class lever?
Move the fulcrum (pivot) farther from the effort and closer to the load.
What is an example of a mechanical advantage?
Crowbar (lever) .
