The garden hose is a backyard version of the same problem engineers and operators deal with every day: how much flow can you get through a real system, and what does it cost you in pressure?

This Spillway Failed On Purpose

💾

An overview of fuse plug and fusible gate spillways
⚙️ Check out SendCutSend for custom parts fabricated from your CAD: http://sendcutsend.com/practicalengineering

Most of the largest dams in the world have gated spillways with whole teams of staff dedicated to their operation. But it’s still a challenge, especially for small owners like cities. So there is another option, kind of in between controlled and uncontrolled spillways, and its use is growing worldwide.

How Earthquake Bearings Work

💾

An overview of seismic base isolation for buildings

Earthquakes are such a challenge in engineering: unpredictable both in time and intensity. But I love this solution of base isolation because it’s so intuitive. It’s something my five-year-old would come up with: just put a suspension system on a building.

Do Retention Ponds Actually Work?
