Homework Help Overview

The discussion revolves around the representation of force vectors F1 and F2, specifically in the context of their components along the x and y axes using trigonometric functions. The original poster seeks guidance on how to draw these vectors based on given magnitudes and angles.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants inquire about the definitions of F1 and F2, emphasizing the need for clarity on these vectors. There is also a suggestion to establish a coordinate system to facilitate the plotting of the vectors based on their components.

Discussion Status

The conversation is ongoing, with some participants providing initial guidance on how to approach the problem by suggesting the use of trigonometric functions to determine the vector components. However, there is no consensus on the complete method for drawing the vectors yet.

Contextual Notes

Participants note the importance of defining the force vectors clearly before proceeding, which indicates a potential gap in the original poster's information. The thread has also been moved to a different category, suggesting a shift in the level of discussion.

Homework Statement


F1Cosx and F2CosX2 and
F1Sinx and F2Sinx2

I need to draw each force vector as an arrow ?
how do I do that?

You need to tell us what F1 and F2 are before we can be any help. Without definitions, these are no more vectors than I am a top hat.
 
oky, f1=100 x1=20degree
and f2 200 x2=30 degree
 
Well, pick a coordinate system (say the x-y axis). Then the force F1=(100cos20, 100sin20). Since these are just numbers, you can plot the point (100cos20, 100sin20). Join this point to the origin, and you have your force vector. Similarly for F2
