4 cards from this section. Quick, good the night before a test.
What is the formula for stress?
Look for how the force is dealt with in relation to area.
Define strain.
Think about how length changes in relation to its starting point.
What does Hooke’s Law state about stress and strain?
Recall the definition of Hooke's Law.
True or False: Poisson's ratio is the ratio of lateral strain to longitudinal strain.
Think about how materials deform under stress.
A tensile tester pulls a sample of aluminum with an original length of 50 cm and a cross-sectional area of 0.002 m². If a load of 3000 N is applied, calculate the elongation of the sample if Young's modulus is 70 GPa.
Ensure to convert GPa to Pa for the calculation.
A concrete beam subjected to a compressive load shows a maximum normal stress of 18 MPa and a minimum normal stress of 6 MPa. Calculate the average stress and the radius of Mohr's Circle.
Utilize the formulas for average stress and radius effectively.
