### Unexpected Results from my Transfer Function

I have a system that can be modeled with the following picture: There is a mass $m$ connected to a spring $k$ and a dashpot $d$. These are both connected to another dashpot $c$. A force $F(t)$ is ...

### Does the terminal velocity of a sphere in free drop increase with increasing diameter?

I was trying today to calculate the terminal velocity of a hailstones with increasing diameter and mass. I was trying to figure out if larger hailstones will have a higher impact velocity or lower. I ...

### How to determine the linear and angular velocity of one end of a rod that is pinned on a track on each side?

I am working on trying to determine the velocity of one end of a rod that is pinned on both ends into two different tracks. One track is linear and the pinned end has known values. The other side is ...

### How does 2nd gear create more thrust than 1st gear?

Let’s analyze a vehicle parallel to velocity and forces applying on it. The 1st gear has a maximum velocity value after which you can’t accelerate more. It means that thrust force on wheels generated ...
