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.
The mechanical advantage of a second class lever?
... is always less than 1 .
Why is the output force of a second-class lever always greater than the input force?
Because of the lever's mechanical advantage.
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
Why is a nutcracker is second class?
A lever that has the load between the fulcrum and the effort is known as a second order lever. Once again, the further away the effort is from the fulcrum and the load the greater the mechanical advantage of the lever.
Which type of lever always increases mechanical advantage?
second class lever
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.
The mechanical advantage of a second class lever?
... is always less than 1 .
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.
Why is the output force of a second-class lever always greater than the input force?
Because of the lever's mechanical advantage.
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
Why is a nutcracker is second class?
A lever that has the load between the fulcrum and the effort is known as a second order lever. Once again, the further away the effort is from the fulcrum and the load the greater the mechanical advantage of the lever.
What is the mechanical advantage formula for a 1st class lever?
fd=MA
Which statement is true about the ideal mechanical advantage of a third-class lever?
mechanical advantage is the output force divided by the input force
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.
Mechanical advantage of a 3rd class lever?
always less than 1
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
