Which of the following is a characteristic of a Class 3 lever?
The effort is between the load and the fulcrum.
The load is between the effort and the fulcrum.
The fulcrum is between the effort and the load.
The effort and the load are at the same point.
In a Class 2 lever, where is the load located?
Between the effort and the fulcrum
At the end opposite to the effort
Next to the fulcrum on the same side as the effort
At the same point as the fulcrum
If the mechanical advantage of a lever is 1, what does this indicate about the input and output forces?
The input force is twice the output force.
The output force is twice the input force.
The input force is equal to the output force.
It is impossible to determine without more information.
