Answer

Explanation:

Step1: Recall mechanical - advantage formula

The formula for mechanical advantage (MA) of a machine is $MA=\frac{\text{Load}}{\text{Effort}}$.

Step2: Identify load and effort values

The load is the weight of the crate, which is 100 newtons. The effort is the force exerted to lift the crate, which is also 100 newtons.

Step3: Calculate mechanical advantage

Substitute the values into the formula: $MA = \frac{100}{100}=1$.

Answer:

B. equal to 1
