What is the mechanical advantage of the class 1 lever?
Input = 45 N
Output = 90 N
a
2
b
12.5
c
.5
d
67.5
e
4050
The mechanical advantage of a class 1 lever can be calculated by dividing the output force by the input force.
In this case, the output force is 90 N and the input force is 45 N.
So, the mechanical advantage is:
Mechanical Advantage = Output Force / Input Force
= 90 N / 45 N
= 2
Therefore, the mechanical advantage of the class 1 lever in this scenario is 2.
