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

AI Thread 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?

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 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
