What does these structures do? (pistons with linear and circular motion)

[Femme_physics]

I always see them in my dynamics problem but I never understand what are they used for, typically? Just to get some sort of perspective on the thing.


It's supposed to be a rod connected to two pistons moving with linear and circular motion

Do you mean what are these objects useful in real world ?
I think almost nothing. It's just for practising with exercises.

Your picture is similar to a sliding garage door mechanism (but drawn upside down).

There are many applications for these types of linkage. See http://en.wikipedia.org/wiki/Mechanical_linkage (and the links to Watt's linkage, etc on that page)

Really? Wouldn't we be better off studying something more practical?

This helped clear it though :) -->
