What is the mechanical advantage of the class 1 lever? Input = Effort Output = Load a 12.5 b 2 c 67.5 d 4050 e .5

Answer 1

The mechanical advantage of a class 1 lever is calculated by dividing the load by the effort. In this case, the load is 67.5 (c) and the effort is 12.5 (a).

So, the mechanical advantage of the class 1 lever is:

Mechanical Advantage = Load / Effort
= 67.5 / 12.5
= 5.4

Therefore, the mechanical advantage of the class 1 lever in this case is 5.4.
