Thermal Expansion Demo: Bimetallic Strip

This demonstration uses a bimetallic strip to illustrate the differences in the thermal expansion coefficients of different materials.
This demonstration was created at Utah State University by Professor Boyd F. Edwards, assisted by James Coburn (demonstration specialist), David Evans (videography), and Rebecca Whitney (closed captions), with support from Jan Sojka, Physics Department Head, and Robert Wagner, Executive Vice Provost and Dean of Academic and Instructional Services.

it's wonderful to have visual experimental experience of thermodynamic theories. thanks to people like you.

[@anshulkeote5466]

I fee l bad for how much propane he wasted in the beginning

What the hell bruhhh are you a psychopath?

Ohh yes its really irritating

[@eliassuna2430]

Imagine you saw this after the current gas price surges😂

[@scott3013]

Propane was not wasted in this video. Having the torch on throughout the video was more entertaining than the alternative.

[@floodsexists106]

hmm why do use the gasoline before it starts

What application does this contraption have?

[@bryanchin88]

Analog thermostats use bimetallic strips to trigger whether the Air Conditioner turns on.

[@gitesh22]

MCB , miniature circuit breakers

Thanks

Wastage of gas video instead of bi metallic strip demo

[@rio_agustian_]

Cool

[@SameerMashyalkar-lm7ec]

How to buy it

[@gloryB-3]

Can I use a blow dryer to heat metal to expand it?

[@atomicplayboy6680]

not sure if that would be hot enough but you could probably use a candle flame or lighter. It will take longer to heat than the flame in this video

[@vigneshkumar9378]

You cant, needed a flame for visible changes

[@crazgaming5236]

nice

does not explain why tho

make a video but dont know the metals??🤦🏻‍♀️🤦🏻‍♀️

why did you sigh at first? ARE YOU OKAY??? ARE YOU TIREDDDDD

[@Moonlightshadow-lq4fr]

for dummies should be the title. How the heck are these 2 pieces stuck together would be a useful question and he didn't even say what the other metal was. So this is how schools teach things these days, some dude considering himself superior dancing around a bent file by the looks of things!

[@_winston_2503]

speak faster and don't waste propane

[@Help-Leo]

The saddest person ever

[@silentmode]

What wasteful behavior! You could have light up the torch just moments before you conduct the experiment and not the entire 55 seconds while you are talking.

He sounds very nervous and over-pronounces things a lot. He needs training on how to present things, because he's not doing a good job at it.

[@ashwattdoeseverything429]

Yea shut up atleast he is not a complainer like u

[@GlidyBun]

Be quiet. He is doing a fantastic job.

[@PlatinumEagleStudios]

@@GlidyBun No thanks, I'll pass. But thank you for your kind offer. You're so sweet 😘
