F1X = F1 COSQ= 61COS 17= 85.3N
F2X = F2 COS Q = 38 COS 64 = 16.7N
F3X = F3 COSQ = 54COS(8+90) = -7.52
FX4 = F4 COSQ= 93 COS(53+90) = 56N
وهكذا................
F1X = F1 SINQ= 61SIN 17= 17.8N
F2X = F2 SIN Q = 38 SIN 64 = 34.2N
F3X = F3 SINQ = 54SIN(8+90) =53.5N
FX4 = F4 SINQ= 93 SIN(53+90) = 56N
وهكذا ..............
