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 would increase the mechanical advantage of a first class lever?
Move the fulcrum (pivot) farther from the effort and closer to the load.
How is the mechanical advantage of a lever determined?
The 'ideal' mechanical advantage is length of the effort arm/length of the load arm .
What is the relationship between distance from the fulcrum and the mechanical advantage of a first class lever?
The mechanical advantage of a First Class lever is Distance of the effort from the fulcrum/Distance of the load from the fulcrum
What class or classes of lever always have a mechanical advantage greater than 1?
A second class lever always has a mechanical advantage greater than 1.
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 is a fulrum?
an aid used to increase or decrease the mechanical advantage of a lever
What can be increased on a lever increase it's mechanical advantage?
Effort Arm

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) .
