Approximating a Gimbal using Springs and Dampers

In my "day job" I do a lot of (mostly nonlinear!) dynamics modelling and simulation of mechanical systems. One thing that always raises a "red flag" for me is degrees of freedom with no mass, ...

What is the maximum force needed to move the roller block from point A to point B and where does that maximum force occur?

Since you will be using a guide, then my thoughts are the following. Assume at some point the rod forms an angle $\phi$. General Idea Since you are pushing up the platform the downward component of ...

State Space Model of a transfer function

I assume that the above information of the system gives me the transfer function of the compensator only. This doesn't match with the problem statement. The dynamics of a physical system is given by....

How is a mechanical system designed and tested without building a physical model?

Not sure how you've gotten on but I'm in the same boat and have gotten stumped... "it will entail gears, linkages and actuators" I believe is very difficult for the hobbyist. This level of modelling ...

Mapping of vehicle to its horn sound

the mismatch between the horn sound and the size of the vehicle is a very useful way to gain attention. My Suzuki GS1000 carries a pair (!) of Italian sports car horns, tuned to two different notes, ...

Supporting a Chain While Its Size is Varied

Consider having a "loop" of chain on an idler pulley that can move to add / remove slack and sprung or weighted (gravity is free) as necessary : this could be on the return side. Edit: This image ...

Thin film sheet-resistance (van der Pauw method)

As van der Pauw noted in his original paper, the incisions in the cloverleaf shape "substantially reduce the error due to the finite dimensions of the contacts" compared to simple circle. A ...
