One or more of the following statements is/are true. Select which statements are true.

  • 3D Elasticity theory makes the assumption that plane sections remain plane whereas the Euler-Bernoulli beam theory doesn’t make this assumption.
  •  In Euler-Benoulli beam theory, the Poisson's ratio is assumed to be zero.
  • If we have four nodes instead of three, ANSYS will need to determine 8 parameters (4 y-displacements and 4 rotations) either from the essential boundary conditions or by solving a set of algebraic equations. 
  • We have to determine the y-displacement of the midline at locations between the nodes using interpolation. This interpolation is given by a second-order polynomial.
