A body can remain non-rotating only if all the moments acting on it sum up to zero. For a body to be in rotational equilibrium, it is necessary that
If we restrict ourselves to 2D problems, simplifies into
Sum of clockwise moments = Sum of anti-clockwise moments
A hinged uniform rod of length L is held stationary at an angle of 22° by two forces: F1 and F2 applied at the end and midpoint of the rod respectively. Calculate the ratio of the magnitude of F1 to F2.
