How often does a civil engineer use vectors?

Click For Summary

Discussion Overview

The discussion centers on the relevance and application of vectors in civil engineering, particularly in relation to structural engineering and the understanding of forces and moments. Participants explore how often vectors are utilized in various engineering tasks and the foundational knowledge required for civil engineering students.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions the necessity of vectors in civil engineering, expressing uncertainty about their practical application in the field.
  • Another participant emphasizes the importance of vectors in structural engineering, noting that understanding forces and moments, which are vector quantities, is crucial.
  • It is suggested that mastering the basics of vectors, including finding components and resultants, is essential for civil engineers, particularly in structural contexts.
  • A participant critiques the initial question, implying that a fundamental understanding of vectors is expected of engineering students and essential for broader engineering practice.
  • One participant references a physics professor's perspective that using energy concepts is a convenience rather than a necessity, suggesting that force-based approaches are more fundamental.
  • A later reply introduces the concept of virtual work, linking it to kinetic and potential energy, and highlights its significance for structural engineers.

Areas of Agreement / Disagreement

Participants express differing views on the necessity of vectors in civil engineering, with some asserting their importance while others question the relevance of the initial inquiry. The discussion remains unresolved regarding the extent to which vectors are used across different civil engineering branches.

Contextual Notes

Some assumptions about the foundational knowledge of civil engineering students are present, and there is a lack of consensus on the practical applications of vectors in various engineering roles.

Title says it, I was discussing this today with my buddy in physics lecture today. We just moved onto kinetic energy and universal gravitation and they seem to do the same thing a lot better and more efficient.

As a civil engineering major, when will I ever use vectors in my line of work?
 
Engineering news on Phys.org
civil engineering has many branches , one of which is structural engineering. Since structural engineering deals with forces and moments, which are vector quantities, a basic knowledge of vectors is extremely important in that field. It is most important to know how to find the x, y, and z components of a vector, and how to find the resultant of vectors. So you need to master the basics of vectors, which involves generally a basic knowledge of trigonometry and the pythagorean theorem. You don't have to be a genius. Just master the basics of PHY 101. If you do a web search on vectors, especially Wiki, it might scare the living daylights out of you. But for the most part, civil engineering is not like that.
 
Strange question from a Civil engineering major, I will bet your professors would be appalled to hear the question asked.
I'd expect he/she could easily answer their own question.
Put another way: how useful is any engineer who does not understand the basics of vectors?
I suppose you might spend your career in roading, & have no personal direct need for vector analysis; but more than likely you will want to take part in the broader engineering community, & you might well find yourself directing the efforts of young engineering graduates in a variety of disciplines.
 
My physics professor told us ''energy to explain problems is for people who don't understand how to do it using forces'', and that you can answer everything with forces, but energy just makes it more convenient.
 
Skwissgaar, I wonder what your professor would say about the principles behind virtual work? This theory is derived from using kinetic and potential energy. Kind of important theory for structural engineers.
