Question

In the simplification of the loading system, the net force acts at the ___________ of the loading body.

(a) Centroid

(b) The centre axis

(c) The corner

(d) The base

I got this question during an internship interview.

I would like to ask this question from Reduction of a Simple Distributed Loading topic in portion Force System Resultants of Engineering Mechanics

Answer 1

Right answer is (a) Centroid

To explain: In the simplification of the loading system the net force acts at the centroid of the loading body. That is if the loading system is in the form of the triangle then the at the distance 2 by 3 of the base the net force of the loading will act. And the load will be half the area of the loading.
