Homework Statement
Express F1 and F2 in cartesian vector form
Homework Equations
The Attempt at a Solution
I feel fairly confident in my work for F2 but F1 not so much. Especially the j component of F1. I assume my F(1x) component runs from the z axis to the tip of F1 and my F(1k) component runs from the tip of F1 to the line below (which forms the light blue triangle). F(1y) runs along the y-axis and forms the base of the dark blue triangle (I think). Any help would be much appreciated!
F(1x)= -300cos60 = -150lb
F(1y) = 300cos60sin45 = 106lb
F(1z) = 300sin60 = 260lb
F1 = -150i + 106J + 260k
F2 = 50cos60i + 500cos45j + 500cos120 = 250i + 354j - 250k
