two forces 20N each are inclined at 100 degree to each other.find the single force that will; replace the given force system balance the given force system
α =(360⁰ - 2•100⁰)/2=80⁰
F1 is directed along the positive X-axis ,and F2 is 100⁰ measured from
the positive X- axis with the counter-clockwise, F is 230⁰measured from
the positive X- axis with the counter-clockwise
