adamaero · Answer

I got F_1 = 43354 N
or does in cancel out (the kg and the m/s^2)?

adamaero · Answer

on page 20 (it's already linked for you)
I only have a question about a part of a question (about F_1)

perl · Answer

one minute , reading this :)

adamaero · Answer

it's either a mistake on my part of not understanding how the units transform 
or a simple mistake on the authors part

perl · Answer

Do you agree that
4/5*F1 + 0 - 5*9.81 * cos(45 degrees) = 0 ?

adamaero · Answer

Okay? So I should just treat kg as not multiplying the number by 10^3?
in this case, 5 kg as just 5 not 5000, right?

perl · Answer

right, because force in SI uses newtons, and 1 newton = 1kg * m/s^2

perl · Answer

1 N = 1 kg * m/s^2

adamaero · Answer

thanks, that was my question
