the resultant of two forces is 250n and the same are inclined at 30 n 45 with resultant,one on either side.calculate the magnitute of two forces.
For the sake of simplicity lets assume
sorry forum bug...Let the two forces be F1 and F2 and resultant be R.Lets assume F1 lies on x axis So if F1 is on x axis , F2 will make 75degrees with x axis and resultant will make 30degrees with x axis.So balancing the force components we get andRemember we can find the value of sin75 and cos75 by applying formula of sin(a+b) and cos(a+b). a =45 and b = 30Solving we get F2 = 129.4Nsubstituting value of F2 in first equationF1 = 183N
