    Constant Inertial
AI Thread Summary
The discussion focuses on calculating the inertial constant (k) for a system comprising a sphere and four disks. The formula I = kMr² is central to the calculation, where M is the mass of the flywheel and r is its radius. The Parallel Axis Theorem is suggested as a method to aid in this calculation, particularly when considering the distribution of mass as weights are added. There is confusion regarding the implications of increasing mass on the concentration of mass and its effect on the inertial constant. Additionally, an increase in angular acceleration (alpha) is linked to an increase in spin velocity.

I = kMr 2
Where M is the mass of the flywheel, r its radius and k is its inertial constant.
Can I calculate my own inertial constant( a sphere + 4 disks around the sphere)

Thanks Help will be appreciated

So in short I am adding weight on the side of the ball .. as mass of the wieights is increased concentration of mass is distributed more... so I decreases. I am confused I don't understand the parallel axis theorm. An an increase in alpha would obviously mean an increase in spin velocity? Yes?
 

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...
