Of course glass bends, and if you have a thin bit (eg 0.3mm) it bends quite
significantly without breaking.

For a start the steel is probably only 1mm thick, if that, and that sort of
thickness you can usually bend over your knee with your bare hands.

Mechanical advantage:
power = input force * input speed = output force * output speed.
Example is having a tiny electric motor geared down by several orders of
magnitude driving a press.
You could get a 100W motor (the sort in those hand-held food mixers), gear
it down a huge amount and you could get pretty much whatever force you
wanted (of course the higher the force, the slower it will move down).
