Challenge Problems
Push your limits with advanced challenges
A material has a Young's modulus of 70 GPa and is used as a beam in construction. If a load of 5000 N is applied and it deforms by 2 mm, calculate the length of the beam.
💡 Hint: Use the Young's modulus formula to relate all knowns and unknowns effectively.
An aluminum wire has a diameter of 2 mm and a length of 1 m. If it is stretched by 100 N, determine the elongation. (Young's modulus for aluminum is 70 GPa.)
💡 Hint: Calculate area first, then substitute into the equation for elongation.
