#### Answer

$f_{s,max}$ increases as more force is applied to the crate.

#### Work Step by Step

The equation to guide the thinking in this problem is: $f_{s,max}$=Coefficent of Friction$\times$Normal Force The coefficient of friction remains constant throughout the experiment, and the normal force has a direct relationship with $f_{s,max}$. This means that as normal force increases, $f_{s,max}$ increases. When more force is applied on the crate normal force increases, meaning that increasing force on the crate increases $f_{s,max}$.
