1. The problem statement, all variables and given/known data An object has two ropes attached. One is on the x axis (positive) with a 60 lb force. One is 120* (Quadrant II) from the first rope with a 30 lb force. I have to find the resultant force and angle using the component vector method of addition NOT the parallelogram method. 2. Relevant equations Fa + Fb = R 3. The attempt at a solution I set up a table of components, but I am not sure if they are correct. I am just really confused as to how to approach this problem. I know how to do it using the parallelogram method, but it seems like some important piece of information is missing for doing it using the component vector method. A=30 lb B= 60 lb Angle A=120* Angle B=0* Ax = ?? Bx = 60 lb Ay = ?? By = 0
welcome to pf! hi argentnox! welcome to pf! (try using the X_{2} icon just above the Reply box ) to find the component in a direction, always multiply by cos of the angle to that direction
Thank you, I will try that and see how I do. If it is okay, I will probably come back to make sure I got the correct answer. I figure if I got the answer correct, I must have done the work correctly. ;)
