“structural engineer to design a new beam so that a load-bearing wall can be removed on a renovation project”…“Which of the following diagrams accurately depicts the shear forces that the beam will be subject to?” I selected “Correct. Simply supported beams experience shear” but the results say I failed that question.
The shear diagram for a uniform loading looks like this:
The shear diagram for a point load looks like this (point load in middle):
The shear diagram for uniform load and point load (point load in middle) looks like this.
Interesting that twice I have selected the correct answer on 2 specific questions and the result always shows incorrect and a different selected answer. I even printed out the question to review later.
