Homework Statement
[/B]
The door is held open by the means of 2 chains. If the tension in AB and CD is Fa = 300 N and Fc = 250 N, respectively, express each of these in Cartesian Vector Form
Homework Equations
Sin / cos / tan
The Attempt at a Solution
The angle of FA at B is atan(1.5sin30/(1+1.5cos30 )) then +y direction force A is 300cos that angle and -z direction force is 300sin that angle
There are 2 forces in 2D but I don't understand the 3D. There are 3 forces x, y and z
