Question

PLEASE HELP!!! REALLY CONFUSED AND HAVE HOMEWORK DUE TOMORROW! The three concurrent forces acting on the screw eye produce a resultant force Fr=0. If F2=(2/3)F1 and F1 is to be 90 degrees from F2, determine the required magnitude of F3 expressed in terms of F1 and the angle theta.

Answer 1

can you draw a picture of what is going on ?

Answer 2

let me add an attachment, thank you for checking my question out! its the 4th problem.

Answer 3

First step is break force f1 into x and y components



use trig to find the x and y components.
can you do that ?
