SPRING.

[Audio] INTRODUCTION What is?? Springs are elastic components used to store and release mechanical energy. Is it Important? Fundamental to many engineering systems, they absorb shocks and reduce vibrations. Brief History: Springs have evolved from wooden structures in the Bronze Age (bows) to advanced metal designs today..

[Audio] Types of Springs Tension Springs: Close-coiled, used for pulling forces, like in door hinges. Compression Springs: Open-coiled, resist compressive forces, seen in pens and mattresses. Torsion Springs: Resists torque, common in clothespins and mousetraps. Flat Springs (Leaf Springs): Absorb energy via bending, used in vehicle suspensions. Spiral Springs: Store torque in instruments like clocks. Conical Disc Springs: Handle high loads in limited spaces, like industrial machinery..

[Audio] Material Characteristics Hardened steel is commonly used for its strength and resilience. Other materials: Stainless steel (corrosion resistance), titanium (lightweight), and beryllium copper (non-magnetic). Properties to consider: Strength: Ability to handle loads without permanent deformation. Heat resistance: Ensures performance in high-temperature environments. Corrosion resistance: Critical for outdoor or marine applications..

[Audio] Applications of Springs Daily Use: Pens, mattresses, garage doors. Industrial Use: Suspension systems in vehicles, shock absorbers. Precision Instruments: Watches, weighing machines, and measuring devices. Aerospace: Springs in control systems and landing gears. Medical Equipment: Prosthetics and dental braces..

[Audio] Inspection and Testing of Springs Importance of Inspection: Ensures safety, functionality, and longevity. Types of Inspection: Visual Inspection: Check for cracks, corrosion, or deformation. Example: Rusted springs in outdoor applications. Dimensional Inspection: Verify length, diameter, and coil spacing. Tools: Calipers or micrometers. Load Testing: Measure how the spring compresses or stretches under a load. Example: Testing car suspension springs. Fatigue Testing: Simulate repeated stress to evaluate durability. Example: Door hinge springs under continuous use.
