Component forces on angle bracket

Click For Summary
SUMMARY

The discussion focuses on resolving forces acting on an angle bracket, specifically calculating the x and y components of these forces. The user initially defined axes and attempted to find the resultant force's magnitude by summing the components. A critical error was identified in the calculation of the x-component for a 175 N force, emphasizing the importance of accurately defining the acute angle rather than relying solely on cosine values. Correctly determining these components is essential for solving the problem effectively.

PREREQUISITES
  • Understanding of vector resolution in physics

The Attempt at a Solution


Ive begun by defining an x and y axis, followed by find the sum of x-components of the forces, and y-components. Followed by the magnitude of the resultant force. The only method i could think of was to find the total result moment of the x-components and let that equal to F.d, where F is the x-component of the total reaction force, and then do the same for the y-component to find the where it intersects BC.

Your working image is very hard to read. There's not so much calculation here that you couldn't type it out in the edit box.

In any event, it looks like you have calculated the incorrect components for the 175 N force to start with. You've got to pay attention to where the acute angle is defined and not just blindly assume that the cosine of the angle gives you the x-component of the force.
