Question

If the supports are not properly aligned then the reaction forces developed are adequate to support the body.

(a) Statement is true only in 2D

(b) Statement is true only in 3D

(c) Statement is false throughout

(d) Statement is true only in 1D

This question was addressed to me during an internship interview.

I'm obligated to ask this question of Equilibrium in Three Dimensions topic in portion Equilibrium of a Rigid Body of Engineering Mechanics

Answer 1

The correct choice is (c) Statement is false throughout

Best explanation: This is the basic nature observed during the experiments on the beams an all the support system. The dimension doesn’t affect the equilibrium conditions. The main motto is to achieve the equilibrium. It is achieved by equating the net force equal to zero. But here the system is not properly aligned.
