Like "leverage" but for distance moved at the end instead of force.
Are you thinking of "mechanical advantage"? And yes, I know that's two
words.

Moment? Not movement, moment. Maybe there's another word that
goes with it. https://en.wikipedia.org/wiki/Moment_(physics)
Moment still refers to forces. I believe that Command Crackpot was
looking for a word that scaled distances rather than forces. The
phenomenon where, if you look at the distant stars, you can move your viewpoint at greater than the speed of light.

Known in popi relativity texts as 'the lighthouse paradox'.
But nothing really moves at that speed.
For mechanical motion you have the whiplash effect,
for the fact that the tip of the whip can go faster than sound,

If you mean rotating a long stick (or rod) in such a way as to describe
an arc about a fulcrum point, the word you are seeking is "moment".
It's hard to see how any amplification via distance (or mechanical
advantage) can be gained by rotating a "long stick" in a twisting motion.

It's very easy. The whip is a prime example. You can't move your hand
as fast as the end moves.

Well its still leverage but you are effectively changing it the other way around. Its like turning a gear from the other end in that its going to be harder as you are moving things faster from a smaller motion instead of the other way around.

I'm not sure if there is a word that describes the opposite of leverage
in mechanics. However, I found a source that suggests that the word **"mechanical advantage"** can be used to describe both conceptsĀ³. A
lever amplifies an input force to provide a greater output force, which
is said to provide leverage, which is mechanical advantage gained in the system, equal to the ratio of the output force to the input forceĀ¹. The opposite of this would be a reduction in force in favour of an increase
in movement at the end of the leverĀ¹.

While it was certainly an add-on for 3 and 4 speed gearboxes (often
usable in more than one gear), 5 speed boxes were introduced to many
vehicles specifically to incorporate the overdrive from the outset. Many
such car handbooks state that 4th gear is 1:1, with 5th being an
overdrive, with maximum speed usually being attainable in 4th.

In a "traditional" car (engine in the front driving the back wheels)
it's a step-up gear instead of just passing the drive through the
gearbox directly in "top".
In some cars it's electrically actuated and can be engaged in 3rd or

have a step down to the final transmission anyway in the front or rear
differentials.
While it was certainly an add-on for 3 and 4 speed gearboxes (often
usable in more than one gear), 5 speed boxes were introduced to many
vehicles specifically to incorporate the overdrive from the outset. Many
such car handbooks state that 4th gear is 1:1, with 5th being an
overdrive, with maximum speed usually being attainable in 4th.
Never heard of such a thing.
If I was to drive full speed in 5th then
engage 4th, I'd overrev the engine.
Although not often used that way, leverage is perfectly valid for the reversed (to convention) action of a lever. It is just that the
mechanical advantage will be <1.
You should get out more.

Other than they would have to be correspondingly large to get a usable reduction.

They did have fixed track bikes back then too but very few were crazy
enough to ride them on the street like the current minor fad.
It wasn't simultaneous but I managed to blow both on a very long winding downhill run. If I'd spit on the rims they would have sizzled. Disk brakes rule.

cars have a step down to the final transmission anyway in the
front or rear differentials.
While it was certainly an add-on for 3 and 4 speed gearboxes (often
usable in more than one gear), 5 speed boxes were introduced to
many vehicles specifically to incorporate the overdrive from the
outset. Many such car handbooks state that 4th gear is 1:1, with
5th being an overdrive, with maximum speed usually being attainable
in 4th.
In the end its just words.Ā What speed do you want to drive the
final shaft to the differentials at?
Not necessarily just words, when the highest gear gives better fuel
consumption but a lower top speed than the next highest.
Except that most manufacturers chose the diff ratio so as to give the
cars maximum speed in top gear and with four speed boxes 1:1 in top.
When adding a fifth gear, it was specifically for more relaxed and
efficient cruising and *was* an overdrive.
For example Ford boxes from the time when 5-speed boxes began to be introduced:
For 4 cylinder engines, Type 3, Type E, Type 9 and for 6 cylinder
engines, type 5 iron and type 9 long shaft, all have different gearing,
but in every case 4th is 1:1 and gives maximum speed.
Those boxes that had a 5th gear introduced (both type 9s), introduced
0.82:1 - above the existing 4th (top) gear, but with a lower top speed.
Today, maybe none of the gears give 1:1, but you can be sure that "top", giving maximum speed, is not the highest gear (the ratio will be
dependent upon the diff ratio) - with one or two gears effectively
serving the purpose of overdrive - no matter what their actual ratio.
In the video he got up to 64 km/h.
A typical cyclist can pedal at a cadence of 120 revolutions per minute
Hence they can achieve 64km/h with normal 50/10 cogs.
I was surprised to see a bicycle with pneumatic tires on wooden rims in a museum but apparently you can still get them.

I had thought it was a museum related to the fort but the article mentions the upgrade to metal rims because wood didn't stand up well.

I have one of these since I wanted a full sized folding bike, not one of
the ones with tiny clown wheels. The hype is it was developed for military use but I have no idea if it was ever used in that context. It does work
well and I can carry in the car rather than on a rack exposed to weather
and theft.

rear differentials.
While it was certainly an add-on for 3 and 4 speed gearboxes (often
usable in more than one gear), 5 speed boxes were introduced to many
vehicles specifically to incorporate the overdrive from the outset.
Many such car handbooks state that 4th gear is 1:1, with 5th being an
overdrive, with maximum speed usually being attainable in 4th.
In the end its just words. What speed do you want to drive the final

Not necessarily just words, when the highest gear gives better fuel consumption but a lower top speed than the next highest.
Depending on other constraints, you can change the overall box ratios
and the differential and get exactly the same result.
Yes, but you stell get the peak speed below the highest gear ratio -
ssuming you've designed the ratios to incorporate the effect of overdrive.
I thought 6 speed boxes were the norm these days anyway.
6, 7 or even more.

Not necessarily just words, when the highest gear gives better fuel
consumption but a lower top speed than the next highest.
Except that most manufacturers chose the diff ratio so as to give the
cars maximum speed in top gear and with four speed boxes 1:1 in top.
No they didn't. They will have chosen gear ratios dictated by overall
cost in all likelihood.
Cost and saleability. And, since the same vehicle would probably not
come with the same engine in all models, they might tweak the ratios or
final drive ratio to get all in line.
When adding a fifth gear, it was specifically for more relaxed and
efficient cruising and *was* an overdrive.
Not really. No.
For example Ford boxes from the time when 5-speed boxes began to be
introduced:
For 4 cylinder engines, Type 3, Type E, Type 9 and for 6 cylinder
engines, type 5 iron and type 9 long shaft, all have different gearing,
but in every case 4th is 1:1 and gives maximum speed.
Those boxes that had a 5th gear introduced (both type 9s), introduced
0.82:1 - above the existing 4th (top) gear, but with a lower top speed.
One swasllow doth npot a summer make. What Ford bodged on the cheap onto
existing gearboxes to save fuel and redesigning the rear differential
back in the 1980s is not what is current today
Today, maybe none of the gears give 1:1, but you can be sure that "top",The 'purpose of of overdrive' is a notion you seem to have invented.
giving maximum speed, is not the highest gear (the ratio will be
dependent upon the diff ratio) - with one or two gears effectively
serving the purpose of overdrive - no matter what their actual ratio.
There is no 'overdrive' in a modern car. 'overdrive' was always a
strapped on extra unit. Today we have 5,6,7 and 8 speed gearboxes and of course the highest ration are - in a production saloon - designed to
match the most efficient engine RPM with somewhere about the legal
motorway speeds..
Or whathever 'mpg' figures are tested at .
So what? Marketing is everything.

There is no overdrive in your case. Its simply a matter of gear ratios. Naturally you will gear the top gear to be most fuel efficent at highway cruise speeds.
