# Equation 2

Expand the following: \begin{align} ΣF_{AY}=0 =&\cssId{Step1}{F_{AY}-mg-Mg=0}\\[3px] &\cssId{Step2}{F_{TY}=+mg+Mg}\\[3px] &\cssId{Step3}{F_{TY}=g*(m+M)}\\[3px] \end{align}

1. Firstly, to calculate FAY you need the weight multiplying the gravity because It's static so the resultant is the normal force.
2. Secondly, we pass the mg and Mg to other side so It's positive.
3. Thirdly, we put it as the gravity multiplying the sum of the weights.
