Homework Help: Concurent Parallel Forces

  1. Jan 26, 2006 #1
    I have a problem where i have found the angle for one line but i cant find the angle for the other. See attached picture i couldn't find how to add the picture to the post without a url for it. so far i have the x and y values for two line im only missing the third line.
    f1 = 1570 lb ^x 0 lb ^y
    f2 = 532 lb ^x 1740 ^y i got 17 degrees as an angle for this line
    fr=

    without the angle i wouldnt be able to add Fr it would be FRCOs? FrSIn? how am i supposed to add that??

    add the x components of the first two vectors (this is the x component of the Fr vector)

    add the y components

    these two are your components of the Fr vector
