00:04:09.260,00:04:12.260
Benjamin Strong: I dont believe we finished the problem but i don’t remember where we left off

00:07:27.055,00:07:30.055
David Lont: Is this a new example?

00:07:32.418,00:07:35.418
Scott Miller: No

00:07:39.619,00:07:42.619
David Lont: Thanks

00:08:16.348,00:08:19.348
Tyler Bye: How do you go from Tn being a column in the last lecture to a row in this lecture? 

00:09:51.008,00:09:54.008
Tyler Bye: Yes

00:13:49.595,00:13:52.595
Tyler Bye: cross product of a and b

00:13:51.672,00:13:54.672
Ethan Reid: take the cross product of a and b

00:13:54.522,00:13:57.522
David Lont: Look at the calc 3 notes

00:14:34.499,00:14:37.499
Righa Righa: no sorry 

00:19:52.758,00:19:55.758
Nicole Badour: Is Tn just the traction vector or does the n mean it has something to do with the normal?

00:21:33.029,00:21:36.029
Ron McGee-Sinclair: should that be [42.55- 1.80 +10.10]?

00:22:08.887,00:22:11.887
Ron McGee-Sinclair: thank you

00:24:44.135,00:24:47.135
Joel Parker: Traction should equal sqrt of N and S

00:24:49.253,00:24:52.253
Joel Parker: Squared*

00:36:24.135,00:36:27.135
Jeremy Baiocchi: To be clear the length of the vector is not changing just the way we describe it to have a maximum axis value.

00:37:37.265,00:37:40.265
Jeremy Baiocchi: thanks

00:41:11.317,00:41:14.317
Ethan Reid: Looks like we're finding an eigenvalue

00:42:57.787,00:43:00.787
Jeremy Baiocchi: 0,0,0,0

00:43:19.203,00:43:22.203
Steve Nemeth: zero

00:50:54.075,00:50:57.075
Steve Nemeth: yes

00:50:55.433,00:50:58.433
Joel Parker: yes

00:50:55.924,00:50:58.924
Vegard Selnes:   yes

00:50:56.252,00:50:59.252
Ethan Reid: All good

00:50:58.461,00:51:01.461
Leah Harris: yes

00:50:58.539,00:51:01.539
Ashleigh Heath: yes

00:50:58.617,00:51:01.617
Isaac Blickley: yep

00:51:00.594,00:51:03.594

00:51:05.303,00:51:08.303
Hussain Alshowaikhat: yes

00:51:09.320,00:51:12.320
Ray Vigo: yes

00:51:58.695,00:52:01.695
Garrett Clyma: agreed

01:01:43.103,01:01:46.103
David Lont: Parametrize?

01:17:31.230,01:17:34.230
Joel Parker: did you say you had these lecture slides posted somewhere where we can view them outside of lecture?

01:18:16.574,01:18:19.574
Ethan Reid: The slides are in the coursepack that you can buy on an Android

01:18:54.609,01:18:57.609
Tyler Bye: Why when you wrote out the symbolic tensor for finding principal stresses do you have the non diagonal elements mirror each other in tensor notation? 

01:18:58.147,01:19:01.147
Gavin Hutchins: Did you receive my email? I joined the call as soon as I could

01:19:15.854,01:19:18.854
Joel Parker: thanks ethan
