How does the moment of inertia work in this physics question? (Vibrations and Waves by George C. King) [closed]
Not sure if this is just me having a moment where I'm missing something totally obvious, but I'm going over some old undergraduate physics work to reinforce my knowledge, and I've encountered a step ...

Why am I getting this derivation of time period of pendulum in an accelerated frame wrong? [closed]
We are working in the frame of the cart and we are trying to obtain the $\tau=k\theta$ form.
So, let's write the $\tau=I_{axis}\alpha$ first for a small deviation $\theta$ from the vartical.
(The ...

Is projection of a simple pendulum, doing SHM as well?
I know projection/shadow of a Uniform Cirular Motion does SHM, and a simple pendulum also does shm. But I was wondering whether, for a pendulum in $xy$ plane having its central axis parallel to $y$ ...

Does time period of a simple pendulum depends upon the moment of inertia of the Bob of pendulum or its shape?
Time period of simple pendulum is given by
$T=2\pi {\sqrt{\frac{L}{g}}}$
Here L is the length of pendulum i.e. distance between the point of support to the centre of mass of the Bob.
Now consider a ...

Connecting rotational period with period of oscillation
Recently I have been thinking about if rotational period is somehow related to period of oscillation for SHMs. My original question was how velocity of something impacting a spring affects its ...

How do you derive the compound pendulum formula?
How do you derive $$T=2\pi\sqrt{I/mgl},$$ where $I$ is the moment of inertia and $l$ is the length of the pendulum?
Is it even the right formula? How would I derive a compound pendulum formula for a ...

Pendulum similarity with a ball attached to a uniform disk with constant [closed]
A particle of mass $m$ is supported by a frictionless horizontal disk which rotates about a vertical axis through its center with a constant angular velocity $\omega$ . The particle is connected by a ...

Issue about rotational and translational kinetic energy of a pendulum
Let’s say we have a pendulum that consist of a light string hanging a disk-like object. It is allowed to undergo simple harmonic motion with small oscillations.
My question: Is the energy of the disk ...

Oscillating along a circle
Suppose there is a round track which a particle will be traversing (a.k.a vertical circular motion of ideal string). Now we know that if the circle is divided into four quarter circles, there is no ...

Is it possible to get the SHO approximation of a pendulum without using energy conservation?
I tried to get the approximation for small angle of a simple pendulum using only $\sum \mathbf F = m\mathbf a$ and cartesian coordinates (that means only $x$'s and $y$'s, without $\theta$). After some ...

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(...
