A wire of negligible mass has a cross-sectional area of m2. Tensile stress greater than 28 MPa would break the wire. Find the least weight that, when suspended from the wire, would result in the wire breaking. Answer to the nearest newton.
Which of the following is a correct unit of Young’s modulus, ?
Which of the following formulas correctly relates , Young’s modulus of a substance, to , the tensile strain on a wire made of that substance, and , the tensile stress on the wire?
