4 cards from this section. Quick, good the night before a test.
Define stress.
Think about what happens when you apply a force.
What is Hooke's Law?
Remember the relationship between force and deformation.
What is stress defined as?
Think about how pressure is calculated.
True or False: Hooke's Law applies only to materials under large deformations.
Consider the limits of linear behavior.
A steel beam experiences a tensile stress of 250 MPa. If the Young's modulus of steel is 200 GPa, calculate the amount of elongation per meter of the beam.
Revisit the stress-strain relationship.
Consider a cylindrical rod of diameter 10 mm and length 1 m subjected to a compressive force that develops a stress of 150 MPa. Determine the compressive strain experienced by the rod, given that the Young's modulus for the material is 120 GPa.
Understand the relationship between stress, strain, and their importance in material property evaluations.
