Question: Please help me with these animations!

Hi everybody,
I have these two (three) animations (a single animation and a array with two other animations) and I would like to plot the three animations such that when I click on the play button of one of them, all the three animations starts at the same time.. I don't know how to get this, please help me if you can!
This is the code of my animations that I'd want to run at the same time:

The first:


display([mech||(2..nstep+2)],insequence=true,gridlines=true,title="Mechanism Animation\n",
titlefont=[Helvetica,roman,12],scaling=constrained);


(I modified manually the dimensions of this first animation and I would like to mantain the dimensions
 I chose, this is important for me!!)
And the second:


display(array(1..2,[display([mech||(2..nstep+2)],insequence=true,gridlines=true,title="Particular\n",
           titlefont=[Helvetica,roman,12],scaling=constrained,view=[-0.91..-1.025,0.25..0.355],axes=boxed),
                           display([mech||(2..nstep+2)],insequence=true,gridlines=true,title="Particular\n",
           titlefont=[Helvetica,roman,12],scaling=constrained,view=[0.91..1.025,0.25..0.355],axes=boxed)])); 

 
Thanks everybody for help!
