Resolution of Forces

• There are 4 quadrant 

          Quadrant     l ll lll & lV

 l quadrant is (+ , -)
ll quadrant is (-,  +)
lll quadrant is (- ,  -)
lV quadrant is (- , +)
X - axis.& Y - axis.
respectively as shown in Fig

Steps for problem

1. ξfx= ? ( only for x axis) (Symbol N)

[ goes on left  side is negative ,goes on right side is positive+]

 2. ξfy=? ( only for y axis) (Symbol N)

[ goes on upper side positive, goes on down side is negative ]

 3. R=Resultant (Symbol N)

 
√(ξfx)²+(ξfy)²

 4. θ or μ = tan⁻¹ [ξfy÷ξfx]

To Find Resultant and Its Magnitude we can use this 4 Steps
