Question 1
Under what condition does failure occur according to the Maximum Normal Stress Theory?
- When shear stress exceeds yield strength
- When maximum principal stress exceeds yield stress
- When alternating stress is below yield strength
💡 Hint: Think about the definitions of stress types.
Question 2
True or False: Fatigue failure can occur even when stresses are below the yield strength.
- True
- False
💡 Hint: Consider the nature of fatigue in materials.

Question 1
A cylindrical rod faces an axial load of 40 kN. Its yield strength is 250 MPa. Determine if the rod will fail using the Maximum Normal Stress Theory and discuss factors to consider for safety.
💡 Hint: Use the formula: Stress = Force / Area.
Question 2
Design a simple experiment to evaluate the endurances of two different materials under a fluctuating load scenario. Discuss how you will ascertain their Fatigue Failure criteria.
💡 Hint: Consider using strain gauges for accurate measurements.
