Why does a class 2 lever will always have a greater mechanical advantage than a class 3 lever?
Trixiexu
Mechanical Advantage is given by the following equation:
MA = Load
Effort
On a class 2 lever, the fulcrum (pivot) is at one end of the lever and the work applied is at the other end. The load is then applied near the fulcrum, as common with the wheel barrow.
A class 3 lever has the effort applied between the fulcrum and the resistance. Therefore, a much greater effort will be required to produce the same moment value.
A typical C2 lever has a much greater distance in which to produce the load than a C3 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.
Why is the output force of a second-class lever always greater than the input force?
Because of 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
When is mechanical advantage increased by a first class lever?
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
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.
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.
Why is the mechanical advantage of second class levers is always greater than 1?
Because the load is always between the effort and the fulcrum, so the effort arm is always longer than the load arm.
Which type of lever always increases mechanical advantage?
second class lever
Mechanical advantage of a 3rd class lever?
always less than 1
The mechanical advantage of a second class lever?
... is always less than 1 .
When is mechanical advantage increased by a first class lever?
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
Advantage of third class lever?
'Mechanical Advantage' of a 3rd class lever is always less than 1. Force on the resistance is less than the effort force. Distance moved by the load is greater than distance moved by the effort. Eg: fishing pole.
What makes the first class lever second class lever third class lever different?
1st order levers have the fulcrum between the load and effort arms. The mechanical advantage of these levers can be greater or less than 1, depending on the length of the arms.2nd order levers have the load portion between the effort portion and the fulcrum. These always have a mechanical advantage greater than 1. They increase the force exerted at the expense of distance.3rd order levers have the effort portion between the load portion and the fulcrum. These always have a mechanical advantage less than 1. They decrease the force exerted with a gain to the distance.
What is the formula for lever?
(AMA / IMA)100 Where AMA represents the actual mechanical advantage and IMA represents the Ideal Mechanical advantage. AMA = Fr/Fe where Fr equals the force of the resistance from the fulcrum, and Fe equals the force of the effort. IMA = De/Dr where De equals the Distance of the effort from the fulcrum and Dr equals the distance of the resistance from the fulcrum
Why are third class levers used if their mechanical advantage is less that one?
Mechanical advantage is not the only reason to use levers.
