Given : Force of 800N acting at a point.

To Find : resolve this force along 35° on it's one side and 50° on it's another side.​

Solution:

A force of 800N us acting at a point.

Assume that it along x axis

force along 35° on it's one side and 50° on it's another side.​

Force A at an angle     -35°

and Force B at an angle of 50°

ACos(-35°) + BCos50° = 800

ACos(35°) + BCos50° = 800

=> A(0.819) + B(0.642) = 800

ASin(-35°) + BSin(50°) = 0

=> BSin(50°)  = A Sin( 35°)

=> B  = 0.7488A

A(0.819) + B(0.642) = 800

=>  A(0.819) +  0.7488AB(0.642) = 800

=> 1.3A = 800

=>  A= 615.4

     B = 460.8

Force along 35° = 615.4

Force along 50° = 460.8
