Flexural rigidity of echinoderm sperm flagella.
The stiffness (flexural rigidity) of live sperm flagella, Triton-demembranated flagella (axonemes), trypsin-digested axonemes, and doublet microtubules of the axonemes in echinoderms was determined from the relationship between their deformation when a stream of medium was applied and the viscous resistance of the medium acting on the flagellum. The stiffness of the flagellum beating in seawate...
متن کاملFlexural rigidity measurements of biopolymers using gliding assays.
Microtubules are cytoskeletal polymers which play a role in cell division, cell mechanics, and intracellular transport. Each of these functions requires microtubules that are stiff and straight enough to span a significant fraction of the cell diameter. As a result, the microtubule persistence length, a measure of stiffness, has been actively studied for the past two decades(1). Nonetheless, op...
متن کاملRetrieving the Flexural Rigidity of a Beam from Deflection Measurements
A rigorous investigation into the identi cation of the heterogeneous exural rigidity coe cient from de ection measurements recorded along a beam in the presence of a prescribed load is presented. Mathematically, the problem reduces to the need to solve the Euler-Bernoulli steady-state beam equation subject to appropriate boundary conditions. Conditions for the uniqueness and continuous dependen...

متن کاملThe flexural properties of endodontic post materials.
OBJECTIVES To measure the flexural strengths and moduli of endodontic post materials and to assess the effect on the calculated flexural properties of varying the diameter/length (D/L) ratio of three-point bend test samples. METHODS Three-point bend testing of samples of 2mm diameter metal and fiber-reinforced composite (FRC) rods was carried out and the mechanical properties calculated at su...
