Spring constant of a piece of glass

AI Thread Summary
To estimate the spring constant of a standard microscopy coverslip, which measures 25mm x 25mm x 0.15mm, one can utilize the Young's modulus along with plate bending formulas from Roark's formulas for stress and strain. The spring constant can be determined by considering the geometry and constraints of the coverslip, specifically how it behaves under a central force with fixed edges. Calculating the deflection at the center when a force is applied will help derive the spring constant. This approach is essential for practical applications in microscopy. Accurate estimation of the spring constant is crucial for understanding the mechanical properties of the coverslip in experimental setups.

This is a real world application that I'm trying to figure out. I need to estimate the spring constant of a standard cover slip (used in microscopy). The coverslip is a thin glass square, dimensions 25mm x 25mm x0.15 mm. I know the Youngs modulus. How should I estimate the "spring constant" of the slip when a force is applied to the center of the square and all edges have a boundary constraint of 0 motion.

Any help is appreciated.

Look up plate bending formulas in Roark's formulas for stress and strain.
 
Thanks!
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
