19. In general, a concentrated force can only be applied to the node. However, if we use the concept

' 'work-equivalent'' load, we can convert the concentrated load within an element to correspoi ing nodal forces. A concentrated force P is applied at the center of one beam element of length Calculate "workequivalent" nodal forces and moments {Fi, Mi, Fj, M2} in terms of P andL Hint: the work done by a concentrated force can be obtained by multiplying the force by displai ment at that point.
