But applied to academic problems involving point masses, linear springs, and inifinitely rigid bodies :)

No thanks. You seem to be doing the shoveling part.

They do break their legs very easily.
The strength of a bone is proportional to its cross-sectional area. The loading on a bone is proportional to the mass (volume) of the animal. Volume increases more rapidly than cross-sectional area when the animal gets bigger.
Edit: What was unsatisfactory?

Thanks for the nostalgia trip. Brings me back about 20 years.

It's fair within a range. Like comparing a horse to a dog. But not when it's a dog vs an ant.

Unfair comparison when we go to the extremes. Tiny animals are strong simply due to how area scales with respect to volume.
For the same reason elephants need sturdy legs, but not mice.

Kind of. Calculus of variations is typical in structural mechanics, but Lagrange equations specifically are not that important. Double pendulum is perhaps introduced, but not studied really.
My point was mainly that engineers have PDEs and physicists have ODEs in classical mechanics.
