4. Platelets have a microtubule ring as their cytoskeleton that forms a perfect circle of diameter 3 μm and makes the discoid shape of resting platelets. Normal microtubules are essentially hollow tubes with an outer diameter of 25 nm, a thickness of 3 nm and isotropic with a Young's modulus of 2 GPa, a Poisson ratio of 0.3 and can withstand a strain of = 0.03 without breaking. Can these rings be made up of normal microtubules? Explain your answer. Hint: the strain will Platelet microtubule clearly depend on how tightly the rings are coiled, which is determined by the diameter of the platelet. How do you relate the diameter (or related radius) of curvature of a bent bar or beam to the strain in lateral loads? The information you need is in the lecture 10 notes summary, but If you are still stuck, review the derivation of how bending moments create longitudinal strains (video 10a or lecture notes 10).
