3. A cylindrical metal rod of 50mm diameter and 3m length is subjected to a tensile load of 150KN. To what length the cylinder should be centrally bored on one side to reduce weight by material removal, so that the total extension will increase by 20 percent under the same pull. The diameter of the hole being bored on one side is equal to 25mm. Take E= 200GPa.
