Question

The design of the beam requires the knowledge of the variation of the ____________

(a) Internal shear force

(b) Rolling forces

(c) Rotational forces

(d) External forces

I got this question by my school principal while I was bunking the class.

I'd like to ask this question from Shear and Moment Equations and Diagrams topic in division Internal Forces of Engineering Mechanics

Answer 1

Right answer is (a) Internal shear force

To explain: The design of the beam requires the knowledge of the variation of the internal shear force. Because beams are the structures which are being made so as to support the loadings which are perpendicular to the axis of that structure. And to support properly the area must be uniform.
