WebNow, we need to express w3wo in terms of R. To do this, we can use the moment equation: ΣM = 0 where ΣM represents the sum of moments about any point on the beam. We can choose the point where the concentrated load is applied as the reference point, since it simplifies the calculation. ΣM = 0 (R)(L) - (woL)(L/2) - (w3wo)(L/4) = 0 WebTherefore the direction of the moment vector for the flagpole example is into the page. This is called the right-hand rule. Sum of Moments .
