Question 1
A cylindrical steel specimen with an initial diameter of 10 mm is subjected to an axial tensile force of 50 kN. Assuming pure elastic behavior, what is the engineering stress induced in the specimen?
Correct Answer:
636.6 MPa
Question 2
During a tensile test on a metallic bar with an initial gauge length of 50 mm, an applied stress of 210 MPa produces an elastic elongation of 0.05 mm. What is the Young's Modulus (modulus of elasticity) of the material?
Correct Answer:
210 GPa
Question 3
In a mechanical stress-strain diagram obtained from a standard tensile test, what does the yield strength (límite elástico) represent?
Correct Answer:
The maximum stress the material can sustain before permanent plastic deformation occurs
Question 4
A structural steel alloy has a yield strength of 400 MPa and a Young's Modulus of 200 GPa. What is its modulus of resilience (elastic strain energy storage capacity per unit volume)?
Correct Answer:
400 kJ/m³
Question 5
A material specimen experiences an engineering stress of 300 MPa under a tensile load with a corresponding engineering strain of 0.10. Assuming uniform deformation without necking, what is the true stress in the specimen?
Correct Answer:
330 MPa
