### How can I find effective force of Rotated frame?

I have frame on below figure. I want to fix bead at the point $(0,0,R)$ with a new rotated reference frame. Then I'll find $F_{eff}$. But I'm stuck since new frame is not rotating but rotated. The ...

### How to find effective spring constant of system which is neither series nor parellel [closed]

I have a spring mass system like this. The spring constant of every spring is $k$, every angle is $120^{\circ}$. Then how do I find the effective spring spring constant of the system?

### Equation of motion in a paraboloid

I am not a physicist I started reading a book about Lagrange and Hamilton equations, where is easier to solve physics exercises than using the usual Newtonian method. But maybe I have some concepts ...

### How does position change if the damping force depends on velocity squared instead of linearly? [closed]

How would a graph of the motion of a spring over time change if the initial damping force depended linearly on velocity was changed to depend solely on velocity squared? and why would it change in ...

### Potential Energy of a Lagrangian System Involving a Mass and Spring

If you were to calculate the potential energy term of the Langrangian for this system, would there be an mg term included, or would it be unnecessary as the change in potential energy of the mass ...

### Choice of origin for calculating potential energy of a spring-mass system [closed]

I know that the point of origin from which we can calculate the potential energy of a particle is arbitrary. However, I cannot see how it's possible is case of a mass-spring system, since the mass ...

### Reason for applying energy conservation and balancing force

I've this question When asked I was told that we will balance force for $2m$ object i.e., $(2\mu)2mg=Kx$ And we will conserve energy for $m$ mass i.e., $Fx=\frac{1}{2}kx^2+\mu mgx$ Both the blocks ...

### Oscillation of a spring and added mass

Why do we need to add a mass to a spring to make a simple harmonic motion in it? Why can't only a spring 'without a mass' make a simple harmonic motion when we apply an external force?

### Hooke's law for atom-to-atom energy well can't be right

Hooke's law says that the potential energy between two atoms is, $V(x)$, for two atoms with distance $r_1-r_0$ is $\frac{1}{2}kx^2$. At room temperature and at equilibrium, water would have an ...

### Equations of motion for non-reciprocal spring-mass system

I am reading this paper. https://www.nature.com/articles/s41467-019-12599-3 The authors derive the equations governing a 1-D mass and spring system with non-reciprocal springs. The final equations, ...

### How can the equation of force for a spring and damper in series simplify to just the equation for a spring if the damper is set to “zero”?

I have been working extensively on modeling physical objects using the stress/strain relationships of springs and dampers as described here: https://en.wikipedia.org/wiki/Viscoelasticity#...
