Van [WayBack] Omrekenen van eenheden/Keuken – Wikibooks omdat ik weer eens van teveel eetlepels naar volume wilde omrekenen:
Omrekenen van veel in de keuken gebruikte eenheden:
dr 1 dr = 0,05 ml druppel tl 1 tl = 5 ml theelepel el 1 el = 15 ml eetlepel kopje 1 kopje = 250 ml ons 1 ons = 100 gram pd 1 pond = 500 gram Afgestreken eetlepels
aardappelmeel 9 g bakpoeder 7 g basterdsuiker 12 g bloem 8 g boter 14 g braadvet 12 g cacao 8 g griesmeel 9 g havermout 5 g krenten 11 g maïzena 8 g margarine 14 g paneermeel 6 g poedersuiker 9 g rozijnen 10 g rijst 13 g suiker 11 g zout 15 g Oventemperatuur

Reminder to politicians: concrete blocks do not help against trucks
Posted by jpluimers on 2019/10/18
These physics lessens at school were useful after all.
TL;DR:
A concrete block of ~1.500kg will loose against a truck of ~9.000kg, especially if that drives 50 km/hour.
It will not stop the truck, but will start moving by itself in unexpected directions and speeds becoming a projectile by itself or worse: usually pieces break off traveling at quite high speed.
The video below shows what happens.
Beton blocks
Over the last year or so, concrete blocks are deployed in many places of the public areas. The usual deeper motivation is to protect against traffic.
The blocks are put on the ground without anchoring for a variety of motivations like flexibility, ease of deployment/removal, cost of blocks (EUR ~100 each) versus anchoring (EUR ~250 per block) in a non-interconnected way.
Often, the rectangular lego-like blocks with 8 bumps are used which come in two varieties: 40cm high (easier to sit on, look more friendly) of a mere 1200kg or 80cm high (look more massive) of only 2400kg.
Other concrete blocks used are roughly the same dimensions, so an average weight of ~1500kg is reasonable.
Trucks
An average truck (at about 10.000 kg) isn’t a static object. In cities they are usually allowed to drive at 50 km/hour, but during assassination attempts they drove much faster and also were much heavier.
Let’s assume however that a truck used is less heavy (not all bad people are smart to get a really heavy truck) at ~9.000kg.
Truck concrete collision
The assumptions so far: a truck of 9.000kg at 50 km/hour against a concrete block of 1.500kg at standstill.
Even though a collision with a truck looses some energy, a moving truck has a lot of it. So most of the energy from the truck will be partially or fully transferred via its momentum to the concrete block(s).
The physics involved here are about momentum:
- momentum = mass * velocity
- momentum in a system is conserved
Before colliding, the truck has momentum, but the concrete block does not. After the collision, the momentum is divided over truck and concrete block so they both have a velocity.
A few cases that can happen, usually in a combined fashion:
- The truck comes to a full stop and all momentum is transferred to the block. The block now travels 9.000/1.500 * 50 km/h which is 200 km/h if it was in front of the truck.
- If the concrete wasn’t fully in front of the truck, the truck will move in another direction as well as the concrete block. Those directions are hard to predict for the public.
- Part of the concrete comes off during collision. Since their weight is smaller, their speed will be higher (because momentum is conserved) and direction even less predictable.

There are many “code of conduct” documents. Often they differ a lot. I have my own: Do not be an asshole. Respect the others.

[WayBack] SchipholWatch op Twitter: “Met app Explane uw klacht naar BAS sturen?”
- [WayBack] Met app Explane uw klacht naar BAS sturen? | SchipholWatch
Met de makers van de site Over mijn dak onderzoeken we de mogelijkheid om onze app Explane uit te breiden zodat iedere meting ook direct als klacht kan worden doorgestuurd aan het Bewoners Aanspreekpunt Schiphol (BAS). Hiervoor zou dan een tweede versie van Explane worden gebouwd, die via Over mijn dak uw BAS-account kan koppelen …
