WebBasically: The internal forces (and moments) for a 2d beam are: shear, normal, and bending moment. There is a positive sign convention to use when making a cut along a beam to determine the forces inside: on the left: shear down, normal out, moment up. Application: A bridge that has different loads applied (from cars, trucks, lampposts, etc). 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
