Three forces - in equilibrium or not?

Click For Summary
SUMMARY

The discussion centers on the concept of forces in equilibrium, specifically analyzing the equation 33Cos(30) - 20Cos(22) <> 0. Participants confirm that the forces are not in equilibrium when considering the left-to-right balance. The importance of including the relevant equations to substantiate claims is emphasized, highlighting the necessity of mathematical proof in physics problem-solving.

PREREQUISITES
  • Understanding of basic physics concepts, particularly forces and equilibrium
  • Familiarity with trigonometric functions, specifically cosine
  • Ability to manipulate and solve equations
  • Knowledge of vector components in physics
NEXT STEPS
  • Study the principles of static equilibrium in physics
  • Learn how to apply trigonometric functions in force analysis
  • Explore vector resolution techniques for force components
  • Practice solving equilibrium problems using equations
USEFUL FOR

Students new to physics, educators teaching force concepts, and anyone interested in understanding the principles of equilibrium in mechanics.

Three forces -- in equilibrium or not?

Hi. I am new to physics and need some help on this question asap. Did I get it right or is it wrong? Correct me if I am wrong. Thank you.

Looks good.
 
You are correct. It's not in equilibrium left to right but your working should really include the equation that proves it. eg...

33Cos(30) - 20Cos(22) <> 0
