Fig. 6. Temporal changes in the forces and moments generated the flagellum and cell. (A) Temporal changes of the thrust resulting in net displacement F_para generated by various types of cells with a flagellum: as h2TF cell with a transverse flagellum of wavenumber of 4.5 (dot-dashed line), h2TF cell with a transverse flagellum of wavenumber of 3.5 (gray line), h2TF cell with a transverse flagellum of wavenumber of 4.0 (solid line) and LF cell with a longitudinal flagellum (broken line). (B) Temporal changes in force in the direction parallel to net displacement F_para, in the hTF+LTF cell generated by the transverse flagellum (dot-dashed line), the longitudinal flagellum (broken line), sum of the two types of flagella (gray line) and drag force by the cell body (solid line). (C) Temporal changes in the moment around the antero-posterior axis of the cell M_para, in the hTF+LTF cell generated by the transverse flagellum (dot-dashed line), the longitudinal flagellum (broken line), sum of the two types of flagella (gray line) and drag force by the cell body (solid line).
