What is the mechanical advantage of the class 1 lever?
Input = Effort
Output = Load
a. 4050
b. 2
c. .5
d. 12.5
e. 67.5
The mechanical advantage of a class 1 lever is equal to the ratio of the distance from the effort to the fulcrum and the distance from the load to the fulcrum. It is calculated as:
Mechanical Advantage = Distance from Effort to Fulcrum / Distance from Load to Fulcrum
Therefore, without specific distances given, it is not possible to determine the exact mechanical advantage of a class 1 lever.
