1. The problem statement, all variables and given/known data Here is the prompt/picture The hint given is a FBD of the bead is recommended to being this problem. Find the coordinates of B so that both the magnitude and orientation of the elastic cord force can be properly represented. Also, two mutually orthogonal normal force directions (to bar AC) need to be included to permit a general representation of normal forces acting on the bead. A shortcut to solving for the elastic cord force can be obtained by writing the vector equilibrium equation, then taking the dot product of that equation with a unit vector pointing in the direction of bar AC. Since the normal forces are by definition perpendicular to the bar, their contribution is zero, and a single scalar equations remains for the for P. 2. Relevant equations ΣFx=0 ΣFy=0 ΣFz=0 Basic trigonometry 3. The attempt at a solution Alright so I started off by finding the coordinates of all the points A (124, 0, 0)mm B (?, 31, 21)mm C (0, 62, 42)mm D (62, 0, 62)mm To find B I made a right triangle with A and C to find the magnitude. Since B is in the middle of AC as stated, I divided the magnitude I found and got 65.5. So B (65.5, 31, 21)mm. I found the unit vector of AC like the hint suggested and found that to be (-0.856, 0.428, 0.290). I am stuck here, I don't know how to go about finding the vector equilibrium. Thank you for any help!
