Question

In triangle distributed loading, the loading at any distance can be easily found by using which of the following trigonometry function?

(a) Tangent

(b) Sine

(c) Cosine

(d) Sine inverse

I got this question during an interview for a job.

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

Answer 1

Right option is (a) Tangent

To explain I would say: In triangle distributed loading, the loading at any distance can be easily found by using Tangent trigonometry function. That is because the linear distance only determines the vertical loading. That is the loading is uniform along the linear distance. Is the linear distance is more the loading is more.
