autoscaling underbrace ?

[mcghost]

hi!

underbrace works pretty fine as long as the part to underline is not to long. if i want do underbrace two integrals Math doesn't underbraces all of it.

{
int from 0 to L {{partial %delta bar u_x}over {partial x}N(x)} `dx `+`
int from 0 to L {{partial^2 %delta bar u_y}over {partial x}^2 M(x)} `dx
} underbrace {"virtual work of internal forces"}

but this works:

{
int from 0 to L xy`dx `+`
int from 0 to L {{partial^2 %delta bar u_y}over {partial x}^2 M(x)} `dx
} underbrace {"virtual work of internal forces"}


so it has to do with the length of the arguement to underbrace.

any ideas how i can underbrace also loooooong arguements nevertheless?

I can confirm this issue: just adding three "x" in the first integral of your "working" example, it doesn't work any more!
