SUMMARY

The discussion centers on the calculation of resultant forces Fx, Fy, and FR in a physics homework problem. The calculated values are Fx = -703N and Fy = 707.8N, leading to a resultant force FR of 997N. However, the provided answer states FR = 867N, indicating a potential discrepancy. The key insight is that the homework only requests the resultant force from F1 and F2, which may explain the difference in results.

PREREQUISITES
  • Understanding of vector resolution in physics
  • Familiarity with trigonometric functions (sine and cosine)
  • Knowledge of resultant force calculations
  • Basic algebra for solving equations
NEXT STEPS
  • Review vector resolution techniques in physics
  • Study trigonometric identities and their applications in force calculations
  • Learn about resultant forces and how to calculate them accurately
  • Practice solving similar physics problems involving multiple forces
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and force analysis, as well as educators looking for examples of vector resolution in problem-solving.

Homework Statement


I have Fx = -800sin60 + 600cos45 -450sin75=-703N
Fy= 800cos60 -450cos75 + 600cos75 = 707.8N
FR = 997N , but te ans given is FR = 867N , is my ans wrong ? or the given ans wrong ?

In the statement only the resultant force of F1 + F2 is requested - maybe that's where the difference is coming from.
