"They’re called crinkle crankles. A single leaf wall over that distance would need brick piers approx every 1.5-2m if it was a retaining wall it would need to be at least 9” wide (2 bricks). The crinkle crankle has more strength due to it’s curved nature so can be 4” wide or a single leaf of bricks. For the maths if we can assume they’re true semi-circles then each semi circle would be 1/2piD or 1.57D whereas a double leaf wall would be 2D for the same length D Therefore using 21.5% less bricks than a double leaf wall hope that clears things up"

Feli,
Correct. But the point is that we know how to make long lasting products, but we don't because we want more money.

#35 two corrections; 45 is tire height as a percentage of the wide + the R stands for the speed rating not the V.

Mindy You are right about the profile (45 in this case) being percentage of the tire width. R19 indicates the radius (i.e rim size if you will); 19 inches in this case.
V is indeed the speed rating (V=240km/h) on the depicted tyre. R is also a valid speed indicator, for maximum speed 170km/h. If R was the speed indicator it would be alone at the end like the V is here.
