Real Engineerings | Engineering & Technology & Gadgets & DIY on Instagram: "Simulation vs. Reality: The "Rotary Hammer" Experiment! 🔨💻 ​In engineering, a design can look perfect in a computer simulation but fail completely in the real world. This video perfectly illustrates the "Prototyping Gap"—the difference between digital theory and physical constraints. ​The Concept: Rotary Impact ​The idea here was to convert the high-speed rotational torque of a power drill into multiple impact strikes.
