A technique used in statics to determine the internal forces in specific members of a truss structure. The method involves making an imaginary cut through the members of interest, isolating a portion of the truss. By applying the three static equilibrium equations ([latex]\Sigma F_x=0[/latex], [latex]\Sigma F_y=0[/latex], [latex]\Sigma M_A=0[/latex]) to the isolated section, the unknown member forces can be solved directly.
