 I'm not an expert but here is my 2nd order ODE.

 {\bf M}_e {\bf \ddot{\vec Q}}_e  \; + \; {\bf C}_e {\bf \dot{\vec Q}}_e
 \; + \; {\bf K}_e {\bf {\vec Q}}_e \; = \; {\bf {\vec F}}_e

M, C, K, F and Q come out bold, subscripts don't and \; is there just
to add some spacing for readablity. I know it may not be standard but
it works and looks like I want it to.
