The main difference between an artillery gun and a mortar is the firing angle - not the projectile weight. Some guns are able to work in both roles due to a big angle range.

That's the problem of doing test only 1 time. No statistics. And the blasts didn't have the same energy at the start position. If anything trench with rounded corners had higher starting pressure, but finished at almost the same number as trench with sharp corners. They should have declared those results inconsistent due to different initial conditions. But then it would be rather unsatisfying conclusion for the show. So they went with rather dubious one. I think it was possible to make a small scale test with explosives making 3 runs of each type of trench. But it is not as spectacular as a full scale blast.

Also, most car accidents aren't going to be a complete stop into a solid wall, going from driving speed to 0 in an instant. Cars often "bounce" to the side. Side impact airbags are mostly designed to prevent you from cutting you from sharp edges. Part of the airbags job is to prevent you from cuts and sharp edges, in addition to cushion the g-force. There was a reduction in g-forces from the balloons. In some car accidents, it could definitely have been enough. The fact that they showed a large reduction from no balloons is proof that it is plausible.

Airbags aren't designed to hold the gas inside the way a balloon does, the safety comes from the controlled deflation in a similar way to the crashbags stunt performers use for jumping off buildings safely. Trenches should really have been twice as long with the explosion in the middle as an explosion at one end is directing the blast down the same way, skews the numbers quite a lot when comparing to the surface control.

I imagine that there's a lot more you could do to mitigate shockwave propagation through a trench. So have the trench step back and forth (at the end of the test trench there would be another two turns to get the trench back in line with the original line of the trench... BUT, have the trench always overshoot the passageway the connects the forward and rearward trenches. That way the blast can partially continue forward into a dead end, and the portion of the blast that travels down the branch to the other line would also split left and right into the dead end here as well.

I'm curious if acute angles in the trenches epuld have further lowered the eave propagation? But logistically, that wpuld have required more digging to cover the same front distance.

Rip Grant. Looked upto you as a child. Still do.

Tbh the ballon test is pretty useless, the reason an airbag works is because its a fixed ballon. During the car crash the "passenger" pushed the ballons out of the way. Which will always be the case for unfixed ballons, it will always just move out of the way instead of absorbing the energy. Now the ballon crusher was also a bad rig, since the baloons were confined to the tube forcing them to actually absorb the load, which wouldn't have hapenned in the actual car, once again they would have simply been pushed out of the way. And the last car also wasnt a perfect comparison since its the first car completely filled with baloons so the baloons couldnt move outof the way. (They basically controlled for it) the last tests with ballons bunched together is fairer since its pretty obvious it cant be compared to the starting test

Season and episode number?

what effect would a slope or ramp have?

Can someone explain why the two angled trenches produced significantly lower numbers on the first 10ft measurement than the straight line trench. The 10ft measurements were all taken before any corners. I can understand why the trench amplifies the blast wave. I would've expected that to be the case. and I can understand why standing at the far end of the sharp angled trench would be the safer option. Again, its what I was expecting But I would've expected the first set of measurements from the blasts in the trenches to be around the same point. They were closer to the above ground test than the straight line though.

@kikixchannel

10 күн бұрын

This is just an assumption, but maybe the corner right after the measuring device had some of the early wave bounce back and mitigate the following pressure surge. In the straight one, the wave had a clear, funneled path all the way to the point where it basically was irrelevant, so the the full, magnified brunt of the blast was able to pass on without interference from itself. Though quite frankly, not knowing the physics behind explosions well enough, I would still expect it being more of a case of accidentally using too much power in the straight one...

I wouldn't be surprised if they did the same experiment several times for each trench to get a spread of varying measurements. The problem with TV is that rigorous stats does not make for great viewing, and they probably had a budget and deadlines to meet so it's just not worth the extra digging and blowing up and filling back in again. Also weren't the walls different? Exposed dirt for one of them. Perhaps the soft surface or rough texture did more to absorb than smooth plywood? The explosive loads may not have been accurately and precisely matched either. Hence the need for more rigour in testing, but that's boring compared to boom time.

2:15 The Germans also had a purely defensive mindset. While they were initially on the attack once trench warfare set in they switched to pure defense as they were on French soil and so they could just wait for the allies to attack them which they did many times. The Germans were fighting a 2 front war and so they minimized troops on the western front as much as possible to sent as many to the east as possible to beat Russia and then launch a massive counterattack on the west once Russia was defeated. This meant that the German Trenches were permanent while those of the allies were temporary.

Ok, just one crucial observation - the clowns were not crashing by a free fall, they had horizontal vector of travel ( where the mass of the car DOES NOT influence the speed of the crash as much as if the car fell vertically).

@@d4slaimless When a car falls, the passengers also 'fall'. There is a difference. If you drive horizontally, there is gravity pulling you downwards, so at a 90 degree angle relative to the direction of the movement. Thus, gravity does NOT magnify the crash rate. In a freefall crash, you are actually adding the force of gravity to what you accumulated thanks to the speed. Result is, there's more G's affecting you. If you don't believe there's a difference between moving horizontal and vertical, then just think about it. What direction takes more energy to roll a wheel. When you roll it forward or when you roll it down? Yeah. Those are two completely different situations because the forces are interfering in one while they are working together in the other. There's also another part to it, too. If you crash horizontally, all the energy that pushes you forward is dissipated and there's only gravity pulling you downward that remains. But in a freefall, you and the car are still pulled by the gravity 'forward' even after the crash. That adds extra energy throuought the entire event, and that's also extra mass behind you that keeps on pushing you (instead of slowing/stopping as the momentum was absorbed by the destruction of the cars frame).

There's a serious flaw in dropping the car as a test... In a normal car, your body shares the acceleration of the car, which at cruising speed is zero. Then when you hit something that's the starting point of the sudden deceleration. In the clown test, the 'people' are now rapidly accelerating as the car falls, then thrown into sudden deceleration, greatly affecting any possible results.

I think that the main reason why trenches zigzag is to not expose every single soldier to the enemy when and if the enemy enters said trench. A couple of enemy soldiers with a light machine-gun in a straight trench could finish or wound every single soldier in it. Trenches had been used in the past where artillery did not exist. Another thing to remember is that airburst shells reduced the advantages of zigzagging trenches to a significant extent, as the shockwave starts higher up, thus reaching more of the trench system. With that said, against impact and delayed fuzes, zigzag trenches do offer a lot more protection, as the fuzes will initiate upon hitting the trench or shortly after.
