Solve this important SPPU DME Unit 6 numerical — full step-by-step, exam-oriented solution for a compression spring used in a safety valve. Problem statement (covered in video) A safety valve of 60 mm diameter is to blow off at a pressure of 1.2 N/mm². It is held on its seat by a close-coiled helical compression spring. The spring must provide an initial compression (set) of 35 mm and the maximum valve lift is 10 mm. Spring index C=5. Material limits and properties: allowable shear stress = 500 MPa, modulus of rigidity 𝐺=80kN/mm We calculate: Wire diameter, d Mean coil diameter, D Number of active turns, n Pitch of coil, p Plus: Wahl factor, stress checks, solid & free lengths, and a recommended rounded design for the answer sheet. 👉 What you’ll learn in this video How to convert valve pressure and diameter into axial load on the spring. Determining wire diameter from allowable shear stress using Wahl correction. Calculating spring stiffness and active turns to meet required initial compression. Ensuring the free length and pitch accommodate both set compression and lift (avoid jamming). Practical rounding choices for exam-style answers and final checks to show in your answer sheet. 🎯 Why watch this video Exact match with SPPU TE Mechanical — DME Unit 6 syllabus. Exam-focused presentation: writeable steps, boxed final answers, and important checks. Best for end-sem revision, viva prep and assignment help. #SPPU #DME #Unit6 #SpringDesign #CompressionSpring #SafetyValve #MechanicalEngineering #EndSem #SPPUTE #DesignOfMachineElements #EngineeringNumericals #WahlFactor #SpringNumerical Join our “Mature Engineers” WhatsApp Group! https://chat.whatsapp.com/LrtOCWG7hFS...
