Angular Measurement & Bearings | Meridian & WCB vs QB (Lec-05) ​Welcome back to CIVIL GYAN CENTER! After mastering linear measurements, it's time to understand how we find directions in the field. In this lecture, we dive deep into Angular Measurements, the concept of Meridians, and the different systems of Bearings. ​This is a foundation topic for Compass Surveying, and questions from WCB to QB conversion are guaranteed in almost every JE/AE level exam. ​📌 What You Will Learn in This Video: ​Meridians & Their Types: Understanding the reference lines—True Meridian, Magnetic Meridian, Arbitrary, and Grid Meridian. ​Bearings: Defining the horizontal angle between a line and a meridian. ​Types of Bearings: * Fore Bearing (FB): Bearing in the direction of progress. ​Back Bearing (BB): Bearing in the reverse direction. ​The Golden Rule: BB = FB \pm 180^\circ. ​Systems of Measurement: ​Whole Circle Bearing (WCB): Measured from North (0^\circ to 360^\circ). Used in Prismatic Compass. ​Quadrantal Bearing (QB/Reduced Bearing): Measured from North or South (0^\circ to 90^\circ). Used in Surveyor’s Compass. ​⏱️ Video Timestamps: ​Introduction to Angular Measurement True vs. Magnetic Meridian Explained Concept of Bearing & Reference Lines Whole Circle Bearing (WCB) System Quadrantal Bearing (QB) & Conversion Rules Fore Bearing (FB) and Back Bearing (BB) Relationship Common Exam Numericals (SSC JE/RRB JE) ​🚀 Target Exams: ​​​​​​✅ ESE (Engineering Services Examination) ✅ SSC JE (Civil) ✅ RRB JE ✅ UPPSC Polytechnic Lecturer ✅ State AE/JE Exams ✅ GATE Civil Engineering ​🚀 About CIVIL GYAN CENTER: ​​​​​​We provide simplified, conceptual, and exam-oriented content for Civil Engineering aspirants.
