Answer #1

For a Transversely isotropic material There Are 5 Indipendent elastic Constant

EA,ET,vA,vT,GA

The elastic constants which form the stiffness matrix are not directly measured from laboratory tests on a material. One can measure engineering constants like Young’s modulus, shear modulus and Poisson’s ratio from laboratory tests. The relationship between engineering constants and elastic constants of stiffness matrix is also not straight forward. This relationship can be developed with the help of relationship between engineering constants and compliance matrix coefficients.

    Twisting DNA For small torques exerted on a beam of elastic material, there is a linear relationship between the torque and the torsional strain, r- C de/dz, where C is the twist modulus. This is analogous to the bend elasticity worked out in class. Single-molecule experiments using magnetic or optical tweezers allow measurements of the twist elasticity of DNA molecules by systematically winding up the tethered DNA molecule and examining the build up of torque. bead 1 fixed small bead...

    Can someone please help me with D and E. Constants Part A To understand the magnetic force on a straight current-carrying wire in a uniform magnetic field. Magnetic fields exert forces on moving charged particles, whether those charges are moving independently or are confined to a current- carrying wire. The magnetic force Fon an individual moving charged particle depends on its velocity and charge er. In the case of a current-carrying wire, many charged particles are simultaneously in motion, so...
