4 cards from this section. Quick, good the night before a test.
Define stress and strain.
Think about how forces change the shape of an object.
What is Hooke's Law?
Recall the formula C3 = E B7 B5.
What is stress defined as?
It is related to the external force acting over a specific area.
True or False: Strain is a dimensionless quantity.
Consider how strain is expressed as a ratio.
Consider a steel beam subjected to both tensile and compressive forces. Calculate the resultant stress if the tensile force is 2000 N and the area is 0.05 m².
Remember to apply the stress formulas for both tensile and compressive forces.
A rod experiences a tensile strain of 0.005 when a load is applied. If its original length was 2 m, how much has it elongated?
Remember the relationship between strain and change in length.
