Question

help please:

Answer 1

More physics than maths, but the physics forum was dead, so...
Q1. A long bar is subjected to a uniform tensile strain along its length. What is the strain tensor?
Q2. A cube is subjected to a uniform compressive strain as a result of external hydrostatic forces. What is the strain tensor?

Answer 2

Math forum is pretty dead, too, lol

Answer 3

tell me about is;D

Answer 4

1am on the west coast, so everybody all sleepy.

Answer 5

ahh, im in Aus, so it's only late afternoon

Answer 6

Yeah, gotta figure a lot of people would be in America, including myself. I just got nothing to do and I don't want to lay down, lol.

Answer 7

I see no numbers in your problem, so I'm clueless :D

Answer 8

me too, and the book we've got is about as helpful as a wet dinner napkin

Answer 9

Usually why a lot of people come on here. Horrible textbooks + online work that makes no sense. It's amazing how many questions come from students using the same online math labs and such, its ridiculous.

Answer 10

hells yeah! Hey, longshot but any idea what the difference between strain and a strain tensor is? My Book's just showing me a matrix that makes no sense without context

Answer 11

I would only know to ask Professor Google.

Answer 12

true, true, but then sifting the diamonds from the rough ;(

Answer 13

I'm working on your problem...

Answer 14

ur the bomb archie ;D

Answer 15

haha I will be in a couple of mins...

Answer 16

brb

Answer 17

What kind of course is this for?

Answer 18

we're studying youngs modulus in physics, forces stresses and strains and that stuff

Answer 19

Ah. Physics made me think too much, lol. Give me numbers, not words with numbers D:

Answer 20

aw c'mon now, physics is everything, it's your "pure numbers"applied and useful...ish
;D

Answer 21

Lol, physics class was NEVER a "how do I do this?" class, it was always a "what do I do?" class. If you knew the method it was fine, but too many formulas, too much trying to draw what you think the situation is and bleh.

Answer 22

yeah, i'll give u that...
makin a sammich, brb
