Thermal switches in blinkers typically have the resistor and bimetallic switch in series, so the light goes on immediately when you turn the blinker on and turns off once the resistor heats up enough. Also thermal switches in blinkers slow down when a light bulb burns out, as the current through the resistor decreases and it takes longer for it to heat. Relay based blinkers usually speed up when a bulb burns out. And the rate change isn't an accident, it is there so the driver notices when a bulb burns out.

It will speed up. Thermal inertia plays a role in it. If you have 2 bulbs on and send more power though the strip, you end up with more hear stored in the heater and the strip and it goes a bigger distance. If you have less heat, it will open less far apart and cool faster too. I get your logic with the slower turn-on, but tell me, how would it cool down slower and turn off slower if you had less power and thus less heat though it with a single bulb? The thing speeds up.

I gotta say, you earned my subscription. Your format is direct, factual, and well rounded in general. You answered pretty much every question I had about thermocouples, and bi-metallic switches. Thanks for your hard work!

An interesting use you didn't mention: thermal expansion is used to join gears, wheels and other rotating objects to shafts/axles. The wheel and shaft are made to slightly overlapping diameters, then the wheel is heated and expands and the shaft is cooled so it shrinks a bit. The wheel is then slid onto the shaft and when the parts cool down/heat up to room temperature, the wheel grips tightly onto the shaft.

I noticed the music volume when you show your intro logo has been too high for nearly all your videos; it's always jolting, especially with headphones.

Nice stuff, haven't heard of some of the mechanisms yet. Something that I missed would be shrinking bearings, gears, couplings etc. onto shafts by heating the piece and maybe cooling the shaft. They then slip together nicely and after normalizing in temperature they clamp extremely tight together. In a similar fashion there are also heat shrink collets for holding endmills and other tools, there are even special inductive heating devices for inserting and removing the tools from the collet. They are really compact and stiff while also being very precise.

Generally, unless you have the extra equipment or need a really interferenced fit but are limited in heating the outer, cooling the inner is avoided because it will condense water out of the air and you'll end up rusting the parts. One workaround is using a purged box with something like nitrogen. Now there's no moisture in the air.

Thank you again I always learn something new. Ive worked on cars for some 50 plus years and never even questioned how a car thermostat worked. I had always assumed it was a bi metal switch or valve bnever knew it was wax. I know of a factory that produces high temp ceramic insulating tubes used in high tempeture alloy steel production to shield high temp probes from destruction. It would interesting to know more about this subject. I believe the companys name is Mcdaniels corporation. Beaver falls Pennsylvania. I have been curious about using a high temp resistant ceramic coating or solid material to construct a small wood gas stove or rocket stove. I just suspect there may be more to learn. Ben Franklin devoted much study to the design of stoves fire places and chimneys. Other technologys came about and pushed wood out of the picture. Even todays most efficiently designed stoves could be improved by advances and development in material science. Ceramic coatings are applied to the interier wall of motor cycle exaust tubes to reduce external temps and other benifits have are realized. Would it be possible to produce a material with micro sized holes that wood gases when forced through under pressure burned much more cleanly. A stove with a preheat chamber an air tight wood fire below a secondary chambered filled with wood that the wood gas can be cooked out of and then burned at a much cleaner higher temp. I know ceramic grids are already used in wood stoves but can we take this technology to the next level. Sorry to go so long watching your videos get the wheels turning. But isnt that the whole point. Thank you again and have a wonderful day. PS I guess the point of my question is are we getting out all the heat out of the wood thats there to get and doing it as cleanly as possible. Imagine a portable camp stove capable of heating a small amount of water faster than any other known product out there today with no moveing parts other than molicules or maybe just a temp control.

Most thermally activated switches I've seen don't use a separate heating element, but instead rely on the current passing through the bimetallic strip to generate heat.

One of the best examples of this is all of the expansion joints on the SR71 Blackbird. This engineering marvel literally leaked fuel while onto the ground and continued to leak while in the air until it reached high temperatures on its outer skin through high speed flight. There were expansion joints all over this aircraft. They figured this out without computers or calculators using slide rules by hand. To this day this aircraft holds the speed records it has achieved to this day. Amazing what people can do when they are faced with these huge problems that they face.

Anders Celsius used a scale that was "flipped" from what we know today, water freezing was 100 and boiling was 0. There was other temperature scales during this time and few of them actually used freezing and boiling of water, after Anders Celsius death they simply put his name on the scale we know as Celsius today. Anders Celsius did actually make a number of observations about water freezing and boiling at different pressures but that was actually introduced to Celsius scale at a later point.

I'm a massive fan of thermal-flasher *TWINKLING* incandescent Christmas lights, not talking about blinking lights with the red-tipped blinker bulbs. I discovered them a few years ago from a video Technology Connections had made about them and I've been a convert ever since! I think they are visually far superior to LED lights as the twinkling of the flashers creates a very subtle and gentle almost "shimmering" effect in the rest of the non-flasher bulbs as the voltage each bulb receives constantly fluctuates and the twinkling is actually completely random as opposed to more modern LED lights that cannot reproduce the same visual effects, nor can they be completely random as most will just cycle through a handful of regular timings.

I've always wondered why the frequency of a turning light in the car variates with the variation of power consumption (watts) of the bulb you are using.. here is the answer! Great job

Thanks! So short answer yes it does, but how much and how it affects critical bimetallic parts is a complex question, as it is determined by the alloys, the formed shape and even the method of bonding.

very well expained! my favourite bimetallic application is on RTGs. radioisotope thermoelectric generators. in spacecraft the radioactive element is shielded by a panel on a bimetalic spring so when the rtg gets too hot (i.e. the spacecraft is not using the heat), the bimetallic spring actuates the panel and allows the RTG to radiate away the extra heat into space. Not sure but a bimetallic spring may also control a door that lets heat into the spacecraft for heating as well, but i dont remember

You forgot to mention the use of thermocouples in 3D printer nozzles. They are excellent for measuring the temperature within a 0.01 degrees Celsius accuracy and with PID control the temperature can also be regulated within that accuracy. We're talking well over 100 degrees Celsius nozzle temperatures though, but even a few degrees overshoot or undershoot can cause print issues. 3D printing is extremely precise.

Learned so much! Thanks!

I'm 60. So, I have been around for a while. I watched the world change around me and the technology too. Some of the examples shown here are no longer in use. Although interesting and informative. The open flame pilot light is no longer used. Instead, an electrical spark igniter is used. A constantly burning flame is not only dangerous but wasteful too. But the explanation of how it works is spot on. There was a couple of other small discrepancies but not worth mentioning. For a young guy, you're pretty smart.

The bi-metallic balance wheel was one of the first methods of watch and clock self regulation. When it got hotter, which would slow a watch down due to expansion of the balance spring, the balance wheel would contract, moving the moment of inertia inwards causing it to rotate faster.

TIP: Sometimes, when lighting the pilot light in a pool heater, we had to hold a lighter under the thermocouple before turning on the gas. Just trying to light the gas and have it heat up the thermocouple wouldn't work, as the gas didn't heat it fast enough. I have heard this works on water heaters and such other things. KEEP THE GAS OFF UNTIL READY TO LIGHT, or you may be up for a Darwin award.

I woke up this morning wondering about how the different alloys expand at different temperatures and I found a lot of good information. I got a lot of outside stuff done because it was a cool day. Another gift from God. July 5th isn't usually this cool. Anyway everything I learned made me wonder even more things. My 15 yr old Ryobi lawnmower finally needs a blade. I might take it off and figure out how to take some metal off one end and figure out how much I need to take off the other end in order to have that perfect balance. Aliens might abduct me up in their space ship and I might never have to figure it out. Could just buy a blade.

One of the best uses of heat control that amazed me is rice cookers. Because a magnet will fail once it reaches a certain temp you can pair it so it fails at 101 degrees. Because water boils off at 100 degrees it will only turn off once all water in the pot is gone (absorbed/evaporated).

Just one thing about those flasher units for motor vehicle turn signals. Where do you put the blinker fluid? Also, are these flasher units optional extras for BMW owners? :)

People with Jeep Cherokee is often have problem with overheating, the solution I finally found is to use a higher temperature thermostat like 195°F, that allows coolant to remain in the radiator until it is cooled further before flowing in and out of the engine and vice versa that means that temperature transfer is greater than if you use a colder thermostat. Before I thought, maybe using a colder thermostat would help but it’s the exact opposite. Many people have these issues. Here’s the solution.

Hey @New Mind, You have a great video with one glaring exception. The background music laid with dialog is too loud and is distracting from the pace of the piece. The voice of the narrator is good enough to stand on its own.

Very informative videos you have! Can you do another about CVT transmissions?

Just subscribed after watching 2 of your videos! So much to learn thanks for sharing!

The first electrical diagram of the bi-metal switch controlling the resistive element is drawn wrong. It was drawn in parallel. It would need to be in series. The switch would only control the power in .

I should have read the comments before commenting, I said the same thing.

Flasher Holiday bulbs are my favorite! As a safety bonus, thermoflashers shut off individual bulbs that become too hot, reducing the risk of Holiday fires. As an aesthetic bonus, the unpredictable period of each bulb creates a complex dance of seldom-repeating light.
