The modulus of rigidity, also called shear modulus, indi-cates the resistance to deflection of a member caused by shear stresses. The three moduli of rigidity denoted by GLR, GLT, and GRT are the elastic constants in the LR, LT, and RT planes, respectively. For example, GLR is the modulus of rigidity based on shear strain in the LR plane and shear

Next, we quantify the effect of various forces on the gas, namely, gravity, hydrodynamical force, and radiation force (Fig. 13). During the formation of the photosphere, at t = 0, the radiation force is less important by a factor of a few than the other two forces, up to about a decade in radius outside the photosphere.

As a first-order approximation for an estimation of internal dynein force, all cilia were assumed to have the flexural rigidity and shear stiffness previously measured in normal-length wild-type cilia, respectively, EI = 840 pN-μm 2 (mean ± SD = 840 ± 280 pN-μm 2) and k θ = 40 pN/rad (39.3 ± 6.0 pN/rad) Thus, by itself the magnetic force cannot change the magnitude of the particle’s velocity, though it can change its direction. If the magnetic field is constant, the magnitude of the magnetic force on the particle is also constant and has the value F magnetic = qvB sin(θ) where v = | v |, B = | B |, and θ is the angle between v and B.
