Science Fiction or Real Mechanics? | StarTalk

we have a little quiz a little game show

we have a little quiz a little game show I want you to know I want to know where

I want you to know I want to know where

I want you to know I want to know where this mechanical problem is a science

this mechanical problem is a science

this mechanical problem is a science fiction problem or a real-life real

fiction problem or a real-life real

fiction problem or a real-life real mechanical mechanical problem real or

mechanical mechanical problem real or

mechanical mechanical problem real or not is it okay

not is it okay

not is it okay all right there we go being a man yes so

all right there we go being a man yes so

all right there we go being a man yes so is it a real thing is it a real thing in

is it a real thing is it a real thing in

is it a real thing is it a real thing in real life if you have a cracked harmonic

real life if you have a cracked harmonic

real life if you have a cracked harmonic balancer uh yeah you can be cracked

balancer uh yeah you can be cracked

balancer uh yeah you can be cracked Rahman it yeah

Rahman it yeah

Rahman it yeah I’d I would say it’s science fiction you

I’d I would say it’s science fiction you

I’d I would say it’s science fiction you have Monica Lee balance or crankshaft

have Monica Lee balance or crankshaft

have Monica Lee balance or crankshaft and things you’re exactly right it is a

and things you’re exactly right it is a

and things you’re exactly right it is a real coughing the harmonic balancer is a

real coughing the harmonic balancer is a

real coughing the harmonic balancer is a device connected to the crankshaft of an

device connected to the crankshaft of an

device connected to the crankshaft of an engine to reduce torsional vibration and

engine to reduce torsional vibration and

engine to reduce torsional vibration and serves as a pulley for drive belts and

serves as a pulley for drive belts and

serves as a pulley for drive belts and now I have more questions than that

now I have more questions than that

now I have more questions than that actually answered I pay attention to

actually answered I pay attention to

actually answered I pay attention to when they want to have to pay to get my

when they want to have to pay to get my

when they want to have to pay to get my car fixed I’ve never broken my harmonic

car fixed I’ve never broken my harmonic

car fixed I’ve never broken my harmonic no no they’re usually geared they’re

no no they’re usually geared they’re

no no they’re usually geared they’re very very high rel high reliability

very very high rel high reliability

very very high rel high reliability they’re okay well Beth but Neil you like

they’re okay well Beth but Neil you like

they’re okay well Beth but Neil you like this yeah the rate of change of position

this yeah the rate of change of position

this yeah the rate of change of position is ah debts velocity rate of change of

is ah debts velocity rate of change of

is ah debts velocity rate of change of velocity acceleration so the rate of

velocity acceleration so the rate of

velocity acceleration so the rate of change of acceleration is a jerk and

change of acceleration is a jerk and

change of acceleration is a jerk and that’s what will make that okay cool

that’s what will make that okay cool

that’s what will make that okay cool yeah forensics stuff going on there yes

yeah forensics stuff going on there yes

yeah forensics stuff going on there yes all right

all right

all right would it be a real wait just just to be

would it be a real wait just just to be

would it be a real wait just just to be clear so rate of change of position is

clear so rate of change of position is

clear so rate of change of position is speed or velocity and we’ve all familiar

speed or velocity and we’ve all familiar

speed or velocity and we’ve all familiar with being in a constant velocity when

with being in a constant velocity when

with being in a constant velocity when you’re at constant velocity you don’t

you’re at constant velocity you don’t

you’re at constant velocity you don’t feel it so now if you’re accelerating

feel it so now if you’re accelerating

feel it so now if you’re accelerating and you’re positioned yourself and you

and you’re positioned yourself and you

and you’re positioned yourself and you all your muscles are resisting the

all your muscles are resisting the

all your muscles are resisting the constant acceleration then you have a

constant acceleration then you have a

constant acceleration then you have a change in the acceleration that’s a jerk

change in the acceleration that’s a jerk

change in the acceleration that’s a jerk so you feel it and then you punch the

so you feel it and then you punch the

so you feel it and then you punch the brake some more then you’ll feel a jerk

brake some more then you’ll feel a jerk

brake some more then you’ll feel a jerk forward that’s why it’s appropriately

forward that’s why it’s appropriately

forward that’s why it’s appropriately called a jerk so what else you have all

called a jerk so what else you have all

called a jerk so what else you have all right what about defective planetary

right what about defective planetary

right what about defective planetary gears sure defective planetary yes yeah

gears sure defective planetary yes yeah

gears sure defective planetary yes yeah yeah planetary gears where you have a

yeah planetary gears where you have a

yeah planetary gears where you have a Sun gear and planet gears I didn’t know

Sun gear and planet gears I didn’t know

Sun gear and planet gears I didn’t know anything about it you have a three-speed

anything about it you have a three-speed

anything about it you have a three-speed bicycle you have a planetary gear train

bicycle you have a planetary gear train

bicycle you have a planetary gear train that is exactly it they’re the primary

that is exactly it they’re the primary

that is exactly it they’re the primary case with an automatic transmission

case with an automatic transmission

case with an automatic transmission okay very good all right

okay very good all right

okay very good all right what have you had an unmotivated binary

what have you had an unmotivated binary

what have you had an unmotivated binary motivator it sounds like science fiction

motivator it sounds like science fiction

motivator it sounds like science fiction to me us straight-up correct that isn’t

to me us straight-up correct that isn’t

to me us straight-up correct that isn’t Star Wars this device in Troy okay tell

Star Wars this device in Troy okay tell

Star Wars this device in Troy okay tell me one more what do we have a damp flux

me one more what do we have a damp flux

me one more what do we have a damp flux capacitor that is of course real so

capacitor that is of course real so

capacitor that is of course real so there was a documentary called Back to

there was a documentary called Back to

there was a documentary called Back to the Future I highly recommend it I think

the Future I highly recommend it I think

the Future I highly recommend it I think is on new bike
