Great job.. 👍

Thnx bro

I do not understand how you got the numbers for Dx and Dz. When I put the numbers in a calculator Dx~826.15N , Dz~71.03N. I even tried using your approximations rather than the fractions and still never got close to 0 or 1000 for Dz and Dx

unit vector for AC is confusing me? how do we have a j component?

[@Ljsparmy]

it's 0j... no j component

[@tannerkeck8855]

i think Dy would be pointing in the opposite direction to counteract the 400N force
