Question

As the loading is acting in the two dimensions, that is in a single plane. Thus the calculations involved in the trusses are in 2D.

(a) True

(b) False

I got this question by my school principal while I was bunking the class.

My question is based upon Simple Trusses in section Structural Analysis of Engineering Mechanics

Answer 1

Right option is (a) True

For explanation I would say: The loading is acting in a plane. Thus the calculations are done in 2D only. As the equations for 3D are different. Although the use of vectors can make our task easy but still 2D calculations are done for the trusses, as they are acting in a same plane.
