how to do the 3 force and 4 force graphical method using the below data to find the resultant? Then doing the resultant using the component method. And doing the error analysis for three force and four force.

Component method ifn Fry = 15/ Sinen = Mingsinon" X Fax How to old Vectors . Fox = 1FICOsen = mag cosen Graphical Method A is from the Forcetable. M is the mass on the end of the string. 3 force Example /F,1 = IN Q = 75' IF21 = 2N, 02 = 120 Force Equilibrium Tho IF 1 = 1.SN, &, = 1650 Fal = IN, Or = 1750 RI = ( ) + ( 2fry ) OF= O - - Vector Sum SF = R= Resultant = = -E = - [ = Equilibrant ane Of= tanil 4 3 N Force is a vector, It has Magnatude and direction .
