The nanocomposite exhibits river sand - like properties, such as higher shear strength in loose and wet forms. (treehugger.com)
Finally, they go on about how concrete buildings are resistant to the forces of nature, without mentioning earthquakes, where wood is considered the «most suitable material for earthquake resistant construction due to its light weight and shear strength across the grains.» (treehugger.com)
As I did further research I found plenty of people saying that JB Weld as very poor shear strength, which would be required to hold the adapter in place while screwing and unscrewing the new plug. (mechanics.stackexchange.com)
