Question

For axisymmetry solids gravity forces can be considered if deformation and stresses act on _____

(a) X direction

(b) Z direction

(c) Y direction

(d) Parallel to plane

This question was posed to me in an interview for job.

Question is taken from Axis Symmetric Formulation in section Axis Symmetric Solids Subjected to Axis Symmetric Loading of Finite Element Method

Answer 1

Right choice is (b) Z direction

The explanation: Gravity, or gravitation, is a natural phenomenon by which all things with mass are brought toward (or gravitate toward) one another, including objects ranging from atoms and photons, to planets and stars. Gravity forces can be considered if acting in z direction.
