Multiple Force Analysis

If m harmonic forces are introduced, denoted as , , …, , sharing the same excitation frequency ω and applied to nodes k₁, k₂, …, k_m respectively, equation (3.2) becomes

(AIV.1)

Applying the same simplification theory as was used in Section 3.1 yields (AIV.2), which is similar to equation (3.13):

(AIV.2)

Again, the ...
