The discussion revolves around calculating the sum of forces in the X and Y directions, with a focus on vector components and their respective signs based on a standard Cartesian coordinate system setup. The original poster expresses uncertainty regarding their calculations and the interpretation of angles related to force vectors.
Some participants have provided guidance on visualizing the vector components and their signs, suggesting that redrawing the vector may clarify the situation. There is ongoing exploration of the implications of the angles and the correct application of the equations.
Participants note the importance of including diagrams for clarity and emphasize the need for detailed work to facilitate better assistance. There is mention of specific angles and their relation to the coordinate axes, which may influence the calculations.
That's how you'd find the x and y components of some vector V, where θ is the angle made with the +x axis.cdornz said:
According to the diagram, it would be F1.
F1 is 60° below the negative x axis. So will the x-component of F1 be negative or positive?
Looks OK except for the signs.cdornz said:
Hint: Redraw the vector F1 so its tail is at the point of application. Or at least imagine a set of axes with the origin at the tail of F1. That will make it easier to see the signs of the components.cdornz said:
