Question

The determination of the internal loading in the beams for shear stress diagrams is usually done so as to:

(a) Break the beam

(b) Know the length

(c) Know the diameter

(d) Design the beam

The question was asked in an interview.

The origin of the question is Shear Stress Diagram topic in chapter Internal Forces of Engineering Mechanics

Answer 1

Correct answer is (d) Design the beam

For explanation I would say: The determination of the internal forces in the beam is done so as to design the beams as in the application purpose the beams will be subjected to many loads. This will help us to make the beam properly. And also this will ensure that the beams will not break after the loading is done on them. For this another method is the distribution load method.
