Understanding Vibrations in Steel-Framed Structures

Resonance and Its Impacts. Resonance occurs when the forcing frequency of human activities matches a structure's natural frequency, leading to significant vibrations. For instance, walking at 2 Hz on a floor with a 4 Hz natural frequency can cause severe vibrations due to the second harmonic. Designing to avoid resonance frequencies can ...

Sun Crusher | Wookieepedia | Fandom

The Sun Crusher was one of the most powerful superweapons ever devised. It was developed at the secret Maw Installation. The Sun Crusher was a nearly indestructible craft that was no larger than a starfighter,[1] but was capable of unleashing destruction on a magnitude that dwarfed even the Death Star's capabilities. Unlike the Death Star, which destroyed individual planets, the …
