Front (Question)

What is a constraint or stress/force

Back (Answer)

It’s the effect that occurs inside a material due to an external force that deforms it

Front (Question)

Name the 3 types of forces

Back (Answer)

Stretching, compression, torsion

Front (Question)

Definition of tension

Back (Answer)

Occurs when a material is subjected to a farce that lengthens it ( stretching)

Front (Question)

Example of tension and check notes for symbol used

Back (Answer)

Tug of war

Front (Question)

Definition compression

Back (Answer)

Occurs when a material is subjected to a force that compresses or crushes it. Opposite of tension ( pushing)

Front (Question)

Example of compression and check notes for the symbol used

Back (Answer)

Crushing a can, bicycle suspension

Front (Question)

Definition of torsion

Back (Answer)

Occurs when a material is subjected to a force that twist

Front (Question)

Example of torsion and check notes for symbol used

Back (Answer)

Wringing out a cloth

Front (Question)

What is a deformation

Back (Answer)

Result of a force acting on a material due

#10

Front (Question)

Name the 3 deformations

Back (Answer)

Elastic, plastic, fracture

#11

Front (Question)

Elastic definition

Back (Answer)

Temporary change when material is subjected to force or constrains, object will return back to original shape after constraints are removed

#12

Front (Question)

Example of elastic

Back (Answer)

Stretching elastic, jumping trampoline

#13

Front (Question)

Plastic definition

Back (Answer)

Permanent damage when material is subjected to force of constraint, deformation remains once constraints are removed

#14

Front (Question)

Example for plastic

Back (Answer)

Squeezing play-doh, crumpling paper

#15

Front (Question)

Fracture definition

Back (Answer)

Breaking, occurs when a material is subjected to force or constrains

#16

Front (Question)

Example for fracture

Back (Answer)

Breaking a vase, cutting paper

#17

Front (Question)

What are mechanical properties

Back (Answer)

Specific characteristics of a material, determines how material will act or react when subjected to 1 or more types of contraints

#18

Front (Question)

Name all the different mechanical properties

Back (Answer)

Hardness, elasticity, resilience, ductility, malleability, stiffness

#19

Front (Question)

Definition of hardness and example

Back (Answer)

Ability to resist deformation Marble hard, can’t make hole

#20

Front (Question)

Definition elasticity and example

Back (Answer)

Regains initial shape after subjected to constraint Coils in sleeping mattress return in original position after force is applied

#21

Front (Question)

Definition resilience

Back (Answer)

Resists physical impacts Steel frames are added behind wall as to resist impact or trampoline

#22

Front (Question)

Definition ductility and example

Back (Answer)

Stretches without breaking Copper ca be stretched to make coils

#23

Front (Question)

Definition malleability and example

Back (Answer)

Flattens or bends without breaking Metals are malleable to be made into sheets

#24

Front (Question)

Definition Stiffness and example

Back (Answer)

Resists tension without being permanently deformed another term(tensile strength) Crane cable must have enough tensile strength to resist tension placed on it by wrecking ball
