B Clarifying Young's Modulus and Stiffness Equations for Cantilever Oscillation

Click For Summary
The discussion focuses on clarifying the definitions and applications of Young's Modulus (E) and stiffness (k) in the context of calculating the oscillation period of a cantilever. The user seeks to understand if E represents Young's Modulus or stiffness in their equation for the time period of oscillation. There is confusion regarding the definitions, as both terms relate to resistance to deflection. The user emphasizes the need for clarity on whether the stiffness can be calculated using the provided equation. Understanding these parameters is crucial for accurate calculations in cantilever oscillation.

Just want clarification on two equations.

So basically, I want to calculate the time period T of the complete oscillation of a cantilever. I use this equation.

Is E equal to young's modulus or is it equal to stiffness? If it is equal to stiffness, can I use this equation to calculate the stiffness?

Thank you in advance. :)

What is your definition of the parameter that you call "stiffness?"
 
In my case, I think it is the resistance of deflection. However, when I search online that is also the definition for Young Modulus. Yet there's these two different equations which is confusing.
 

Thread 'Ramjet effect on drone'

I am following someone on Youtube who has built a rocket shaped (4 proprllers) drone for the world speed record ... He was having problems with internal heat from electical control gear and battery inside the sealed rocket (about 1kw waste heat) Speed is 500km/hr , I suggested a 4mm hole in the tip of the nose and 8mm hole at rear which should alow sufficient air cooling .. I said this will increase thrust because the air exiting is hotter .. a bit similar to a ram jet ... was I correct...

Thread 'Why would an atmosphere without greenhouse gasses be colder than with them?'

Quick question that I haven't been able to find the answer to. Greenhouse gasses both warm and cool the atmosphere by slowing heat loss to space. But what would happen without GHGs? I read that the earth would be colder (though still relatively warm), but why? Without GHGs the atmosphere would still be a similar mass and still warmed by conduction from the surface, yet without a means to radiate that heat to space. Why wouldn't the atmosphere accumulate heat over time, becoming warmer? How...
