Challenge Problems
Push your limits with advanced challenges
A cylindrical rod made of steel with a diameter of 10 mm is subjected to a tensile force of 5000 N. Calculate the stress developed in the rod and determine if it exceeds the allowable tensile stress for steel, which is 250 MPa.
💡 Hint: Convert units where necessary.
Consider a column made of concrete subjected to a compressive load that causes a volume change of 20 cm³ in its original volume of 2000 cm³. Determine the volumetric strain and discuss its implications.
💡 Hint: Visualize how structures support loads without crushing.
