Good afternoon group friends, I am a beginner in Mathcad, and I am not able to finish a static problem, if you can help me, thank you very much.

What did you expect? You have not defined x and y so you cannot expect a numeric result.

You may let Prime evaluate symbolically, though.

Welcome to Mathcad.

 

Due to PTC's greed, since you are using Prime version 5, many of us cannot see your problem.  Consider posting a picture version as well.

Werner, why the final answer did not show in "m", what I'm missing here. If you had to solve this problem through vectors would you do the same thing I did?

That is due to your definition. You defined rp as rp:=[x y 0] m. This means that x and y, like 0 are just numbers, without units. I would be rp that contains x m, y m and 0 m.

 

If you're interested, you might try to find out what happens if you define rp as rp:=[x y 0] and then solve x and y.

 

Success!
