SUMMARY

In the discussion titled "Concurrent and Parallel Forces 2," participants analyze the resultant force of four concurrent forces, each with a magnitude of 2750 lb, acting at the same point with angles of 30 degrees between adjacent forces. The correct approach involves vector addition, where F1 is aligned with the X-direction, and subsequent forces F2, F3, and F4 are positioned at 30, 60, and 90 degrees, respectively. The resultant force is not zero; proper vector calculations reveal that the components must be summed accurately to determine the resultant force.

PREREQUISITES
  • Understanding of vector addition in physics

Four forces each of magnitude 2750lb act at the same point. The angle between adjacent forces is 30degrees. find the resultant force. I worked it out and got FR= 0 in the x and 0 in the y is that right??

Let's take F1 as X-direction. Then F2 makes 30deg with it and similarly F3 makes 60deg while F4 makes 90 deg or denotes the Y-direction.
Now add the vectors properly - 2750x + 1375*root3x + 1375y + 1375x + 1375*root3y + 2750y. This isn't anyway 0. Why did you get them wrong?
 
i see what ur saying thanks
