SUMMARY

The discussion centers on a triangular loop problem involving the sine function in physics. The user queries the validity of the equation ##\sin(\phi )=1## for different segments of the loop. It is confirmed that while this equation holds true for the ac segment, it does not apply to the bc segment where the sine values are zero, indicating that the force on the bc segment is indeed zero. This clarification is essential for understanding the dynamics of forces in triangular loops.

PREREQUISITES
  • Understanding of trigonometric functions, specifically sine values.
  • Basic knowledge of physics principles related to forces and motion.
  • Familiarity with triangular geometry and its applications in physics.
  • Ability to interpret and analyze equations in a physics context.
NEXT STEPS
  • Study the application of trigonometric functions in physics problems.
  • Learn about force analysis in triangular structures.
  • Explore the implications of sine values in different segments of geometric shapes.
  • Review examples of similar physics problems involving loops and forces.
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and trigonometry, as well as educators looking for examples of force analysis in geometric contexts.

This is a question I got wrong on a test and would like to see if I can get someone to show me how to do it properly. Snapped a pic . See below please. Thanks.

You've written ##\sin(\phi )=1## at the top. And that is true for the ac segment. But is it true for the other two segments?
 
So would the force on the bc segment be zero since the sin(pi or 2pi) would be zero
 
yep, you got it. keep going :)
