So here's a curious little thing...
I noticed the other day that some of the cars in the showroom were
parked on little metal ramps. Now here's the puzzling thing. My car is
only little, and that weighs 1.25 tonnes. Some of the bigger cars surely
weigh even more than this. So these ramps have multiple tonnes bearing
down on them... and they're made from 2mm steel.
Now obviously somebody far, far smarter than me has carefully calculated
how thick the steel needs to be to hold a given amount of weight. But
these things look so utterly flimsy, it looks like you could bend them
with your bare hands. And yet, you can park a car on them, and they
don't even distort slightly.
I am at a loss to explain this.
