Hello, I am having trouble finding the direction of the resultant of this statics homework problem. The picture uploaded is exactly how it is shown in my book. The problem states: 1. The problem statement, all variables and given/known data For the forces shown, S = 3.81 kip, T = 4.73 kip, and U = 3.65 kip. Determine the resultant. The answers to this problem are 8.05 kip @ -169 degrees. 2. Relevant equations Pythagorean Theorem (to find resultant force): C2 = A2 + B2 x-component = cos(angle)*force y-component = sin(angle)*force magnitude of resultant = arctan(y-component / x-component) 3. The attempt at a solution I have gotten the magnitude via trigonometry as such: x-component of S = -cos(33.6901 deg) * 3.81 = -3.17011 x-component of T = -4.73 x-component of U = 0 ______________________________ = -7.90011 y-component of S = +sin(33.6901 deg) * 3.81 = 2.11341 y-component of T = 0 y-component of U = -3.65 ______________________________ = -1.53659 I then used the Pythagorean Theorem to find the magnitude of the resultant: R2 = √(-7.90011)2 + (-1.53659)2 = 8.05 kip I then took the arctan of the y-component over the x-component, which equals +11.0067 deg which is the wrong direction... I am very lost as to why I am getting the wrong direction if I have gotten the correct magnitude. Any help?
