Complete Guide to Chain Surveying Instruments | Surveying (Lec-03) ​Welcome to CIVIL GYAN CENTER! In this video, we explore the physical tools of the trade. Understanding the construction, least count, and specific uses of Chain Surveying Instruments is essential for both fieldwork and scoring high in competitive exams like SSC JE and RRB JE. ​We cover everything from the traditional Metric Chain to precision tools like the Optical Square and Clinometer. ​📌 What’s Inside This Video: ​Chains & Tapes: Deep dive into Metric, Gunter’s, Engineer’s, and Revenue chains. We also compare Cloth, Metallic, Steel, and Invar Tapes (the most accurate!). ​Ranging & Offset Rods: How to maintain straight lines and measure lateral distances. ​Setting Out Right Angles: Comparison of the Cross Staff, Optical Square, and Prism Square (and the geometry behind them). ​Support Tools: The importance of Pegs, Arrows, and Plumb bobs in marking stations. ​Clinometer: How to measure the angle of a slope in the field. ​⏱️ Video Timestamps: ​Introduction to Linear Measurement Tools Types of Chains (Metric vs. Non-Metric) Types of Tapes (Why Invar Tape is special?) Ranging Rod vs. Offset Rod Tools for 90° Angles (Cross Staff & Optical Square) Pegs, Arrows, and Plumb Bobs Measuring Slopes with a Clinometer Exam-oriented "One-Liner" Facts ​🚀 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.
