solution:

$Fx= 22cos45°+ 14 cos30°\\ =27.68 lb\\ along y axis Fy= 22sin45°- 14 sin30°\\ =8.55634 j^ so magnitude is sqrt(Fx^2+Fy^2)\\ =28.97 lb\\ and angle is arc(Fy/Fx)\\ = 17.17 °$

Next we come to calculating the mechanical advantage of a lever. To do this, you divide the distance from the fulcrum, the point at which the lever pivots, to the applied force by the distance from the fulcrum to the resistance force.
