Mechanisms

Is the movement of the box simple and harmonic?

It's a prismatic kinematic pair

isn't the bar between the radii changing length?

In the actual mechanism, bars don't change length.

Please respond

which diagram do you want? this new one looks different. If the bar on the old one is not changing length, then how can you have those two circles?

I'm not understanding what the mechanism even is.

No linkage is changing length. One of the two bars that is rotating in a circle is driving the mechanism and has a constant angular velocity, the other is driven and does not have a constant angular velocity.

Is there anyone here that can just answer my question

go find someone else to do your homework

Asking a question fucktard, can I solve it as two mechanisms?, /sci/ loves to boast about complex bullshit but when it comes to actual knowledge and applying math you guys are absolute turds

>>8449896
Well it looks like both circles are jerking the box back and forth. This is pretty good, you can use something like this in dildos or onaholes!

>>8449896
looks like 1 DoF
1 DoF systems are best solved with Power-Rate method.

Wait do you not even have to solve the dynamics?
This seems like a basic kinematic question.
Use more reference frames!!

>What is, a penis?
That's what ur mom said when b4 I rammed it up her ass.

point on big circle...
R (cos(t k), sin(t k))
point x in block...
|x(t) - R exp(i t k)|^2 = L^2
(x(t)-R cos(t k))^2 + R^2 sin(t k)^2 = L^2
x(t) = R cos(t k) + sqrt(L^2 - R^2 sin(t k)^2)
other circle.. (x-a)^2 + (y-b)^2 = r^2
other bar length G

(x-a)^2 + (y-b)^2 = r^2
|(x,y)- R (cos(t k), sin(t k))|^2 = G^2
solve?

no idea about this stuff...
