Answer

Explanation:

Step1: Recall mechanical advantage formula

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

Step2: Identify load and effort values

The load is the weight of the bricks, which is 1700 newtons, and the effort is the force applied to the pulley, which is 340 newtons.

Step3: Calculate mechanical advantage

$MA = \frac{1700}{340}=5$
