Is There a Mistake in Calculating Vector Components and Angles?

Click For Summary
SUMMARY

The forum discussion centers on discrepancies in calculating vector components and angles, specifically regarding the force vector F1. Participants identify that the x component of F1 is incorrectly stated as 3N, while the correct calculation yields 7N. Additionally, the angle derived from these calculations varies, with one participant obtaining 9.16° and another suggesting a possible misinterpretation of 9° 5 minutes. The conversation confirms that the calculations are straightforward, and the differences arise from miscommunication or notation.

PREREQUISITES
  • Understanding of vector components and their calculations
  • Familiarity with trigonometric functions related to angles
  • Knowledge of force vector notation and representation
  • Basic skills in resolving forces into components

There seems to be problem with the answer to this problem. Weirdly, they get that the x component of F1 is 3N!

Then, when they end up calculating the direction in C, they get 9.5°. I get 9.16°.

Am I the one going crazy? This is fairly straight-forward!

From the 31 "they"calculate, I conclude that F1x is 7N in their calculations. (I get 31.4)
You and I get 9.16 degrees, perhaps "they" write it as 9 degrees 5 minutes ? (I 9° and 6')

Wouldn't worry too much about this, you're no crazier than I am!
