Analysis of Structures - Zero Force Members

Описание: In this video, we break down a classic exam-style problem on identifying zero-force members in truss structures. You’ll learn how to quickly spot zero-force members using equilibrium principles, apply the standard PE exam rules, and simplify truss analysis problems with confidence.

We cover when and why zero-force members exist, including the two key cases you must know for the exam:

Case 1: When no external forces act on a joint with only two members, both members carry zero force.

Case 2: When no external forces act on a joint with three members, and two are collinear, the non-collinear member is a zero-force member.

By the end of this walkthrough, you’ll be able to identify zero-force members quickly, reduce unnecessary calculations, and move faster through structural analysis problems on exam day.

👷‍♂️ Whether you’re preparing for the Structural depth or reviewing fundamentals for the Civil PE exam, this video is designed to sharpen your analysis skills and boost your confidence.
