Challenge Problems
Push your limits with challenges.
Question 1
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.
💡 Hint: Ensure to convert GPa to Pa for the calculation.
Question 2
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.
💡 Hint: Utilize the formulas for average stress and radius effectively.
