Given a force F = 100N, decompose it into two forces. Given that the angle between one component F1 and F is 30 degrees, what is the minimum value of the other component F2,

If you cross F 1 and make a straight line F 1, F 2 is perpendicular to F, and f intersects F 2, it becomes a right triangle
The side opposite the 30 degree angle is F2, which is half of the hypotenuse F, so F2 = 50N
The method is: to make a vertical line, transform it into a special triangle (such as a right triangle, isosceles triangle) to answer briefly
