    dynamic gears

    @1gibson what do you mean magic car person? maybe you were also saying that a continuously variable transmission box cannot exist? or could not imagine the mechanism to create it? Engineering is solving problems, but innovation is about exploring the unknown.

    dynamic gears

    'Can't really grow more teeth on a gear.' why can't you have the teeth increased in number with a mechanism? that will expand the circumference of the gear and at the same time, more teeth will somehow emerge? I am not trying to do something specific, I am just trying to conceptualize that: a...

    dynamic gears

    but instead of doing it with a belt, could you do it with an actual gear? somehow to increase the diameter of a gear (by axons positioned as radii)? can you imagine this happening somehow?

    collision engineering

    we can position them to protect from both frontal and side collisions (placed perpendicularly) as for improving the air bag systems, I would like to know if there is still a big fatal factor the fact that passengers get smashed in rigid parts of the car, like the cockpit, the front window, etc...

    it's frightening that it took many years and deaths for HANS device to be accepted

    collision engineering

    ok, maybe not ejection seats but a mechanism that will move the seat to the top of the car and let the left of the car crash beneath and absorb the whole energy?

    collision engineering

    mmm so what can we think of? maybe energy-absorbing hydraulic cylinders (like train buffer stops) or springs inside the car that will absorb the energy? or ejection seats for cars?

    collision engineering

    1) if you fall with 100mph in this: http://www.youtube.com/watch?v=lb4cItFJ9vg it is apparently not the same as if you fall with 100mph in a cement wall I was thinking of a material like that I understand that there will be still damage, but I wonder if it is the g's that are responsible for the...

    collision engineering

    can we put an egg inside a capsule that is properly designed (with hydraulic mechanisms or anything) and with the right materials in its walls, and then play football with that capsule and the egg won't break?

    collision engineering

    what if the head is secured in a point of the capsule? or if during deceleration, it touches a soft material, that will absorb its momentum? will the damage be the same?

    collision engineering

    by unbreakable, I mean that will not bend either or in general change its shape

    collision engineering

    hello anyone involved in automotive collision engineering? I would like to know: 1) do we have the materials/design/technology etc to create a totally unbreakable capsule or car body ? under velocities that todays car can achieve, like 100mph etc 2) do we have the materials/design/technology...

    dynamic gears

    Thanks, CVT seems close to what I was thinking of. I didn't knew it already existed.
