Materiald

Question 1

What is youngs modulus

Answer 1

Stress÷strain and is the energy a material can take per volume

Question 2

Application of youngs modulus

Answer 2

Used by engineers to see if materials can withstand sufficient forces

Question 3

What is the stiffness

Answer 3

The spring constant

Question 4

What is the youngs modulus equation

Answer 4

E=tensile stress/tensile strain= or Fl/eA

Question 5

What is the unit of youngs modulus

Answer 5

Nm^-2 or pascals

Question 6

how do u find toungs modulus in stress strain graphs

Answer 6

Gradient=youngs modulus in stress strain graph

Question 7

What is elastic limit

Answer 7

The point in which a material startd to behave plastically where is cannot go back to its original shape

Question 8

What is Limit of proportionality

Answer 8

Point where the material stops obeying hooks law but would still return to orignal shape

Question 9

What is the brittle graph of materials

Answer 9

The graph will not expierence deformation but would rather snap
