Solve the given question:
Question: A steel wire of length 2.04mm with circular cross section must stretch no more than 0.240cmcm when a tensile (stretching) force of 400NN is applied to each end of the wire.
Question 1: What minimum diameter dmin is required for the wire?
I need help to solve the above question and express your answer in millimeters. Take Young's modulus for steel to be Y = 2.00 × 1011Pa.
