Chp. 9: What do mean by 'strong'?

Question 1

bend strength

Answer 1

adding upward forces to the center of a material and an opposite downward force to the edges or vice versa until it breaks

Question 2

shear strength

Answer 2

holding each end of a material and twisting it until it breaks, like a screw

Question 3

tensile strength

Answer 3

pulling a material away from each other until it breaks

Question 4

tensile load

Answer 4

applying a weight to create tension in a material

Question 5

ultimate tensile strength (UTS)

Answer 5

when a material reaches it breaking strength

Question 6

yield strength (YS)

Answer 6

load required to permanently stretch a material measured in terms of stress or psi

Question 7

plastic strain

Answer 7

the deformation percentage caused by the yield strenght

Question 8

compressive strength

Answer 8

adding a force on top of a material and “squishing” it until it breaks at an oblique angle

Question 9

measurement for ultimate tensile strength

Answer 9

pounds per square (psi) dividing the weight or load by the cross sectional area

Question 10

stress

Answer 10

the quantity given by the psi force or load (pounds) divided by area (square inches)

Question 11

strain

Answer 11

a dimensionless quantity that is measured by dividing the extension or contraction by the original length, comes out as a ratio

Question 12

stiffness

Answer 12

defined by a quantity as Young’s Modulus

Question 13

Young’s modulus (YM)

Answer 13

stress applied divided by strain produced
