Thank you We sneak And here's your shmoop dooz your

00:06

brought to you by riding a bike once you learn

00:08

how you never forget it's kind of like physics right

00:11

Sort of All right bernie The biker is on his

00:14

daily twenty mile bike ride in which direction to his

00:17

bike wheels generate torque And here the pencil answers All

00:20

right well this this is this Wow bernie is hard

00:24

core a twenty mile bike ride every day Really We

00:27

feel like bragging when we skip the escalator and walk

00:29

up a flight of stairs We're dealing with torque and

00:32

direction That means we're using the right hand rule Don't

00:36

get in a huff Southpaws We didn't say right hands

00:38

rule it's just the right hand rule That's what they

00:40

call it the land of physics right And rule is

00:43

a rule of thumb Show the direction of torque If

00:46

we hold out our right hand in the direction that

00:49

an object is moving and then curl our fingers in

00:52

the direction of the spin like that our thumb will

00:57

point in the direction of the torque In this case

01:00

that means the torque is heading to the left So

01:03

the correct answer is option b We remember way back

01:05

when we were too embarrassed to use our thumbs to

01:08

figure out math problems Numbers bigger than 4 used to

01:10

be tricky for us on that's What toes or for
