1
Q
What is the Young modulus of a material?
A
The stiffness of a material (how easily it is bent or stretched)
2
Q
How do you calculate the Young modulus of a material?
A
tensile stress / tensile strain
3
Q
What are the units for Young modulus
A
Nm^-2 OR Pa (Pascals)
4
Q
What does a high Young modulus mean?
A
The material is stiff/ rigid
5
Q
What does a low Young modulus mean?
A
The material is flexible
6
Q
How do you find the Young modulus using a stress-strain graph?
A
Calculate the gradient of the graph
