Question

All deformations and stresses are independent of _______

(a) Co-ordinates

(b) Number of nodes

(c) Rotational angle, θ

(d) Area

I have been asked this question in an internship interview.

This intriguing question originated from Axis Symmetric Formulation topic in portion Axis Symmetric Solids Subjected to Axis Symmetric Loading of Finite Element Method

Answer 1

Right option is (c) Rotational angle, θ

Easy explanation: The point around which you rotate is called the center of rotation, and the smallest angle you need to turn is called the angle of rotation. The angle of rotation is a measurement of the amount, the angle, by which a figure is rotated counterclockwise about a fixed point, often the center of a circle.
