Maxwell's wheel - moment of inertia vs damping coeff
I am investigating the relationship between the moment of inertia of a yoyo-like apparatus (maxwell's wheel) and its damping coeff. I am adding disks to my yoyo to change its moment of inertia, which ...

Can you intuitively explain the decreasing time-period of oscillation with increasing pendulum length in some cases?
Consider a rigid body suspended about an axis of rotation which, in general does not pass through it's center of mass (COM) and has a moment of inertia (MOI) $0 < I_{axis}$ about that axis. Let $...

Along which axis is the moment of inertia of a harmonically oscillating body calculated?
I have been learning about oscillating bodies and recently stumbled upon physical pendulums.
Now the problem is i don't understand about which axis is the MOI calculated while finding the TIME PERIOD(...

Physical pendulum: moment of inertia vs center of mass
This has been confusing me for a while. Consider a solid, homogeneous rod of mass $m$ and length $l$, hanging from a fixed pivot. Its center of mass is located at $\frac{1}{2} l$, and its moment of ...

Considering moment of inertia - why do pendula $1$ and $2$ have the same resonant frequency? [closed]
This question was given to me during a lecture. The axis of rotation is into the page, such that the pendulua all swing to the left and the right (and I think it would be obvious to note we're ...

Moment of Inertia of Annular Quadrant
I am measuring the moments of inertia for various numbers of annular quadrants placed on a torsional oscillator. I know $\displaystyle{I=\frac{1}{2}M(R^2+r^2)}$ for a whole annulus. If I want the ...

How to determinate the minimum period of oscillation for a physical pendulum? [closed]
A physical pendulum consists of a thin homogeneous rod of length $l$, suspended by a point $O$ at a distance $x$ from the center of gravity ($x<\frac{l}{2}$), oscillating in a vertical plane. For ...

Period of swinging incomplete hula-hoop
I was working on a problem where I had to calculate the period of a swinging incomplete hula-hoop given its center of mass and radius. It only swings with very small amplitude so I considered the ...
