# How large a force is necessary to stretch a 2.0-mm-diameter steel wire (Y = 2.0 ´ 1011 N/m2) by 1.0%?

In order to calculate the force necessary to stretch a 2.0mm-diameter steel wire by 1.0%, we must first determine the Young’s Modulus (Y) of the material, which is a measure of its stiffness or resistance to elastic deformation. For steel, this value is 2.0 x 10^11 N/m2. We then need to calculate the cross-sectional area of the wire using A = pi * (d / […]
