WebPractice questions from Stress and Strain in the same exam. Question 1. Hard. Views: 5,206. A wire of circular cross-section, which obeys Hooke’s law, is used to suspend a basket as shown. The Young modulus for the material of the wire is 2.5×1011 Pa. When a weight of 34 N is added to the basket, the strain in the wire increases by 6.0×10−5. http://physicsnet.co.uk/a-level-physics-as-a2/materials/stress-strain/ create signature in word 2010
