Question

The difference between the two types of loading namely uniformly distributed and the non-uniformly distributed loading is that:

(a) The latter has the involvement of the integration for the calculation of the net force

(b) The former has the involvement of the integration for the calculation of the net force

(c) The latter has the involvement of the differentiation for the calculation of the net force

(d) The former has the involvement of the differentiation for the calculation of the net force

The question was asked in exam.

Question is from Reduction of a Simple Distributed Loading in division Force System Resultants of Engineering Mechanics

Answer 1

Correct option is (a) The latter has the involvement of the integration for the calculation of the net force

Explanation: The non-uniformly distributed loading is using the integration for getting the net force given by it. And the former only need the area or the linear distance of the loading. That is when the distance is multiplied by the uniformly distributed load the net force is obtained. But that is not so with the non-uniform one.
