##
Tension

(Scalar? Vector? or x order tensor?)

### 2nd order tensor

2

##
Strain

(what is it?)

### the percentage of a material that has lengthened or shortened in response to stress applied to it

3

##
Strain

(Scalar? Vector? or x order tensor?)

### 2nd order tensor

4

##
Elastic resistance

(Scalar? Vector? or x order tensor?)

### 4th order tensor

5

##
Elastic resistance

(what is it?)

### ratio of stress to strain

6

##
Stress

(what is it?)

### mechanical force per cross sectional area (f/m^2)

7

##
Young's modulus

(what is it? what is it large in? small in?)

###
the slope of the curve of stress vs. strain

large in steel

small in rubber

8

##
Hooke's Law

(what is it?)

### the linear proportionality of stress to strain

9

## When is something Hookeian?

### when it's Young's modulus is constant

10

##
Curvature

(what is it?)

### the angular change of the tangent line per distance

11

##
Radius of Curvature

(what is it?)

### 1/curvature

Curvature

(Scalar? Vector? or x order tensor?)

### 2nd order tensor

13

## What is a 1st order tensor?

### a vector

14

## What is a 0th order tensor?

### a scalar

15

## Equation relating pressure, tension, and curvature

### P = T * C

16

## Tension is the same thing as...?

### tensile stress

17

##
Electro-osmotic pressure

(Scalar? Vector? or x order tensor?)

### scalar

18

## Auxin's effect on plants (5)

###
-they bend towards light

-the have greater elongation in the dark

-they bend upwards relative to gravity

-branching is inhibited near growing tips

-roots sprout at the bottom of the plant

19

## Auxin does what to shoot sprouting?

### inhibits it

20

## Auxin does what to root sprouting?

### encourage it

21

## The better organic chemistry name for auxin:

### indole acetic acid

22

## types of meristems:

###
-shoot meristem

-root meristem

-lateral meristem

-floral meristem
