Hi Tod, does that mean Trebuchet range can be adjusted by release pin angle? If the only suitable placement was closer or farther from the target you can adjust range. Does closer = more impact force or does the shot pick up momentum as it 'falls' so farther is better? Thanks!

I was thinking the same, particularly in the episode when Tod wanted to hit the cardboard knights and kept moving them between shots without luck and concluded it must have been the machine's fault. not even considering the possible effects of the wind, the bowling balls themselves seem to be a weird choice considering their superficial homogenity but vastly different inner workings. and I wonder what the farmer thinks of all that stuff thrown at the field, all the going back and forth and the possibility of weird ingredients of the projectiiles seeping into the ground...

[@r.michaeldunwiddie2449]

Having watched a number of trebuchets at the Pumpkin Chunkin in Delaware USA I learned that the length of the sling plays an important part of the throw. The Yankee Siege Machine being the best example can throw a pumpkin 1700 yards if I remember correctly. But only when the sling is just right. If the sling is too long or too short the shot will be short of maximum range.

For chasing accuracy, take a look at around @4:13 - as you yank the trigger-rope, the end of the arm moves a lot sideways (maybe a foot?). Could you modify the trigger to either release more easily, or else re-direct the trigger-rope in such a way that it pulls 'down' on the arm, rather than sideways?

[@kjkallio4393]

I hope we get a video that is a call between you and someone who specializes in building/designing trebuchets about the physics and design ideas and what you need to do to yours given the parts that are easy to change and the parts that are hard to change. I recall vaguely from building a 1 meter arm trebuchet as a kid that the goal was to balance the weights until the arm basically stopped moving entirely when it released the payload.

[@thescatologistcopromancer3936]

Excited Tod puts a smile on my face

[@basilbrushbooshieboosh5302]

From the 'previous shots' footage compilation it can be seen that a release angle of closer to 60 degrees gives a further shot than that of closer to 45 degrees. Physics would decree that an angle of 45 would give the most efficient release angle for the furthest shot throw. However the effect of wind resistance, especially when the shot ball is moving at it's greatest velocity at the start of it's path, transfers to reduction of initial velocity and thus initial height gained. Therefore increasing the release angle to closer to 60 throws the shot ball to gain greater height to allow it to have an extended path which in turn allows a greater distance to be gained by the shot. Great work Todd. I watch all of your and Matt E's uploads religiously, and love them. Cheers, Mic Barrett

[@tods_workshop]

Thanks Mic, but I not a physicist, but I suspect at these low velocities, wind resistance doesn't have much to do with it

[@basilbrushbooshieboosh5302]

@@tods_workshop You'd be surprised. But on the angle of greatest efficiency it's easy to see even with common sense that that's right. And wind resistance is the only other external force, the only one. Gravity is accounted for in an ideal system ie. with no air-resistance. Not blowing my own horn, but I am a physics teacher. But honestly, physics is only a whole lot of very common sense. And thanks heaps for all your effort, and a great show.

it should be pointed out that, the range is one thing, the more important is the flat trajectory. to slight a fortified wall, the energy transfer of the projectile is the key, not the distance per se.

[@theinqov]

The mathematics are fascinating. It would be interesting to use some kind of physics software to calculate the differences by adjusting all the variables - lighter ammo for example, would it go further and with more energy due to increased speed, how much weight has to come off to compensate for the extra load in the extended throwing arm, what if it releases a millisecond earlier, all super interesting.

Can't wait to see more trebuchet action! Are there any ancient manuals on field running trebuchets? I can only imagine this is encountered with every trebuchet assembled.

[@tods_workshop]

I don't think so

[@Pystro]

Something I realized: the release (at 2:54 and 4:14) really jerks the arm a lot. If you want accuracy, that needs to be fixed. The easiest fix is to have put a pulley into the plane that the arms swings through to eliminate any sideways forces. A second possible fix would be to have the release mechanism attached on the frame end of that chain, instead of the arm end of it. Also, if you calculate optimal ballistic arches on ground that isn't flat, the generalization of the 45° rule is that "you get maximum range when the impact velocity and the launch velocity are at right angles to each other". (I learned that from this video: kzbin.info/www/bejne/rqjLk4dvedRkiLM ). I don't know if exactly the same holds true for air resistance, but I'd assume it's very close. Given that, the 2nd shot looks like it 's pretty close to the ideal trajectory already. Get a piece of paper with a 90° angle; hold it to your screen at 5:54; that looks like it's at maximum a few degrees off.

[@johnfitzalan3128]

They just never work quite as you expect, it’s all never ending adjustment. I’ve always wondered about the ‘range’ given. You can shoot a long way but at the end of the arc it’s coming down at a heck of an angle probably going to glance of a wall. A bit like the long bows I wonder if our modern pre conceptions about range are different to how they would have used them. Maybe they aimed for a much more direct fire on flatter trajectory. Of course that means getting closer but that’s always the case really, a Calvary raid would cover 400m very fast . Would need to try different angles against a wall to see what happened.

[@NorthDownReader]

4:13 - there was a sideways jiggle as it triggered. Once you have the range sorted, might the wiggle cause lateral accuracy problems?.

It may, but it is hard to avoid

[@loddude5706]

Axially adjustable wooden cam on the frame, driving a captive wooden pushrod & shoving the sling loop free on time? : )

[@blaksson]

The bucket jiggles because you've got it mounted flat on the ground. Trebuchet designs were almost always on wheels with a bit of play back and forth, and that force in the bucket transfers to the base, so instead of the bucket rocking, the whole thing moves smoothly forward and backward from the same force.

[@tods_workshop]

People keep saying this, but actually do we know this? I am not so sure, so can anyone provide good medieval drawings with them on wheels; not fanciful ones.

[@GuitarsRockForever]

Tod, I suggest you try the release at 42 degree. I seem to remember in old days, military tested artillery range and found the longest range at around 42, not 45. Anyway, even it is 45, I think you can give it a little room in case the release is bit late (few degrees higher).

[@tods_workshop]

That is a really interesting point over which I have wondered. The 42 and degree thing is for high velocity projectiles. I am not saying it is not correct, but drag has less effect at lower velocities and this is a very low velocity, so I wonder.....

[@GuitarsRockForever]

@@tods_workshop I wonder how you control the release exactly at 45 degrees? My thinking is, if the release was only slightly late, it ruins the distance. Setting a very slightly lower release at 42 degrees, might be more reliable.

If the counter weight, is the same as the weight as the projectile, would that not sort out the balance? Or am I missing the meaning of counter weight? Could you not adjust the counter weight, instead of the length of the arm?
