measurement of the characteristics and behaviour of such substances as metals, ceramics, or plastics under various conditions

materials testing

rupture of a material too weak to sustain the forces on it

fracture

action or process of changing in shape or distorting, especially through the application of pressure

deformation

the pressure or tension exerted on an object

stress

the pulling apart of an object

tension

making an object longer in relation to its width

elongate

number that describes relative deformation or change in shape and size of a material (change in length per unit length)

strain

to press or squeeze with a force that deforms an object

crushing

decrease in volume of any object resulting from applied stress

compression

a strain in the structure of a substance produced by pressure, when its layers are laterally shifted in relation to one another

shear

strength of a material against the type of yield or structural failure when the material fails in shear

shear strength

the deformation response of a material to forces applied tangentially

inplane shear

maximum load that a material can support without fracture when being stretched

tensile strength

the capacity of a material to deform permanently in response to stress

ductility

testing a materials response to a load placed at one small point testing its ability to deform

hardness testing

a test to determine how much impact force an object can take

impact testing

measure of the ability of a material to transfer heat

thermal conductivity

change in shape or size due to changes in temperature

thermal expansion

natural process that converts a refined metal into a more chemically stable form

corrosion

tendency of a solid material to deform permanently under mechanical stresses

creep

the weakening of a material caused by cyclic loading that results in localized structural damage and the growth of cracks

fatigue

giving way of an object under pressure

yielding

the ultimate failure of tough ductile materials loaded in tension

rupture

a material without capacity to deform without cracking.

brittle

the sudden change in shape (deformation) of a structural component under load

buckling

the capacity of a material or structure to withstand loads tending to reduce size

compressive strength

the area of a two-dimensional shape that is obtained when a three-dimensional object is sliced perpendicular

cross-sectional area

if(prizm._________) { // when sensor is receiving reflected light beam

readLineSensor(3) == 0

if(prizm._______) { // when sensor detects black stripe

readLineSensor(3) == 1

_____{ // infinite loop - stays locked in this loop until reset is pressed

prizm.setRedLED(_____); // flash Prizm red LED on OR off (two different answers)

HIGH, LOW

what does this code do?

void loop() { // beam reflected, no line detected
