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.
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 is the relationship between distance ratio and mechanical advantage?
The mechanical advantage of a lever is the ratio of the length of the lever on the applied force side of the fulcrum to the length of the lever on the resistance force side of the fulcrum. There are three types of levers - class 1, class 2, and class 3.
Why does a class 3 lever does not have the same mechanical advantage of a class 2 and 1 lever?
because they are smaller than the level 3 that's why
What is the mechanical advantage formula for a 1st class lever?
fd=MA
Which type of lever always increases mechanical advantage?
second class lever
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.
What class lever is a pencil?
A pencil isn't a lever at all, unless you are using it to turn force into useful motion. If you use the pencil to write with, it's closer to being a needle reading a record, as it is dragged across a surface, leaving graphite which has broken off of the main core on the paper. For a first class lever, think of a see-saw. For a second class lever, think of a wheelbarrow. For a third class, think of a pair of nail clippers, or of your forearm.
Is it possible for a first or second class lever to have a mechanical advantage less than one or for a third class lever to have a mechanical advantage greater than one?
Second class lever. . . . Always greater than 1 . Third class lever . . . . . Always less than 1 . First class lever . . . . . Can be greater than 1 or less than 1 depending on position of fulcrum.

How do you find the output force of a 1st class lever?
Multiply (the input force) x (the lever's mechanical advantage).
The mechanical advantage of a second class lever?
... is always less than 1 .
Mechanical advantage of a 3rd class lever?
always less than 1
The mechanical advantage of a second class lever is?
idk go ask your teacher
