Moment of Inertia: Wheels Accelerated to 100 km/hr

AI Thread Summary
The moment of inertia of a wheel is determined by its mass distribution and geometry, not by its speed of rotation. When a vehicle accelerates to 100 km/hr and then the accelerator is released, the moment of inertia remains constant as it is independent of the vehicle's motion. Confusion arises regarding which geometric factors to consider in calculating the moment of inertia. The key factor is the mass distribution relative to the axis of rotation. Understanding these principles is essential for accurate calculations in dynamics.

what is the moment of inertia about the wheels , when the vehicle is accelerated upto 100 km/hr and the foot is lifted off the accelerator

Er.. the moment of inertial is not a function of the speed of rotation!

the moment of inertia is a a function of the geometry and the mass of the object, bt in this case i am confused , as in which geometry to consider??

This getting to be confusing. If you know that it is due to geometry, then why did you bring up the motion of the vehicle?

The "geometry" in question is the location of the mass distribution about the axis of rotation.

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...
