Well, thank you for your contiuous help!

Shouldn't that be the second derivative?

Not really. I was given a project in physics to model a sunglass bin opening. I took Differential equations so I should be able to do this...I think. How would you suggest to model this with ODE? Thanks!

What do you suggest to use to solve for time? Thanks for your contiuous help.

One more thing, what if you want to solve for time. Would you use Conservation of energy? And add in the damper and spring forces? Thanks again!

Once again, thank you for your continuous help!

Which equations do not look right to you? Thanks for your continuous help!

Thanks for the quick reply. Torque for torsional spring = k*(change in angular position) Torque for torsional damper = b*(change in angular velocity) Torque for mass = Weight*radius Does this look right? How would you solve for the angular velocity? Also, doesn't the angular acceleration...

Hello everyone! I need to solve the angular acceleration on a sunglass bin on an over head console of a car. The sunglass bin rotates open. It has a torsional spring and gravity that forces it to open and a small rotary damper that slows it down. There is a gear on the sunglass bin and on...
