Where the arrow is some downward acting force at any distance away from the end of the two *'s. The *'s represent bolts holding this thing in place. Each bolt is directly above the other bolt. If You sum the moments about a line in the vertical direction passing through both bolts, you will have a moment caused by the downard force times the distance to that line. But no counteracting moment???? Whats going on here? I know that the sum of the moments about any point must be zero. Isn't it true for any line as well?
