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.

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?

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.

Luxury watches are strange. Few people notice, even fewer care.

Fire-breathing is not the only thing that makes dragons fantasy. They're also way too heavily built to be able to fly.

Many people can't really throw with force and accuracy because it rarely is useful anymore.

Classical mechanics is the only branch of physics where engineers generally have more expertise than physicists themselves.

There is a period around the year 2000 where you can usually distinguish which one of two movies is older based on the CGI and picture quality alone even if they were made only around 3 years apart.

Historical mathematicians must have been quite impractical by nature since they discovered complex numbers before calculus.

When the sun is shining, sunglasses are actually more handy in winter than summer due to the lower angle of the sun.
