with reference to the diagram, at what angle must the 800N force be applied in order that the resultant R of the two forces has a magnitude of 2000N.
We were instructed to use the i,j method.
So, the forces for Fi = 800sin() and Fj = 1400 + 800 cos() and the resultant is 2000N.
This is where i get stuck, a^2 + b^2 = c^2
so 2000^2 = (800 sin())^2 + (1400+800 cos())^2
any help would be great.
