forces and stresses

Question 1

compression

Answer 1

pushing force is applied to either side of the material

Question 2

bending

Answer 2

both tension and compression forces

Question 3

torsion

Answer 3

when a material is twisted

Question 4

tension

Answer 4

when a pulling force is applied to either end of a material

Question 5

shear

Answer 5

acts on an object in a direction perpendicular to its length ( slide over eachother in opposite directions)

Question 6

reinforced meaning

Answer 6

strengthened by the addition of other materials

Question 7

strengthened meaning

Answer 7

made stronger or more rigid to resist certain forces

Question 8

what does bending do to a material

Answer 8

adding curves and arches and tubes can add strength to a product, using a minimum amount of material

Question 9

what does folding do to a material

Answer 9

it adds strength, but also flexibility by enabling a material to bend easily ( think of corrugated cardboard)

Question 10

what does webbing do to a material

Answer 10

strong fabrics made from high strength material are usually woven into flat strips and used for items under high tension

Question 11

what does fabric interfacing do

Answer 11

adds an additional layer to give it structure, shape and support (eg. bend of cap or shirt collar)

Question 12

what does lamination do to a fabric

Answer 12

improves product’s strength and stability. can improve aesthetics by giving a new finish
