How Does Cantilever Length Affect Vertical Deflection?

AI Thread Summary
The discussion focuses on the relationship between cantilever length and vertical deflection under a fixed mass. The independent variable is the cantilever length, while the dependent variable is the vertical deflection. Participants suggest using the Euler-Bernoulli beam equation and mention the relevance of shear modulus in this context. It is clarified that the mass of the cantilever beam itself is negligible for this analysis. The assignment aims to establish a theoretical relationship and verify it through experimentation.

I was to find a relationship between the horizontal length of the cantilever and the vertical deflection when a fixed mass acts on the end of it. So the independent variable is the length of the cantilever and the dependent variable is the vertical deflection i.e. vertical distance. I've been doing quite some research regarding the question but found no solutions that quite fit the the assignment. I was wondering if any of you could help me out? The application of the formula(if there is one) will be carried out by me. Thanks in advance!

Is this assignment intended to have you find a formula to apply? Or is this an assignment to find the relationship experimentally? I ask this because this is a common experimental assignment.

THe formula has to do with something called a "shear modulus."
 
The mass of the beam is negligible. I guess our teacher's expectations of us was to find a relationship and then to verify it by means of an experiment.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
