The mechanical advantage (MA) of a lever can be calculated using the formula:
\[ \text{MA} = \frac{\text{Load}}{\text{Effort}} \]
In this case, the load is 90 N and the effort is 45 N.
Calculating the mechanical advantage:
\[ \text{MA} = \frac{90 \, \text{N}}{45 \, \text{N}} = 2 \]
So, the mechanical advantage of the class 1 lever in this case is **2**.
\[ \text{MA} = \frac{\text{Load}}{\text{Effort}} \]
In this case, the load is 90 N and the effort is 45 N.
Calculating the mechanical advantage:
\[ \text{MA} = \frac{90 \, \text{N}}{45 \, \text{N}} = 2 \]
So, the mechanical advantage of the class 1 lever in this case is **2**.
