# Young's Modulus Problem

A steel wire of length 2.06 m with circular cross section must stretch no more than 0.290 cm when a tensile force of 350 N is applied to each end of the wire.

1. What minimum diameter d_min is required for the wire? Express your answer in millimeters. Take Young's modulus for steel to be Y = 2à?1011 Pa.

#### Solution Preview

We have the relation ship

Young modulus E=Lo*F/(deltaL*A)

wherer E=young modulus (Pa)

F = force (N)

Lo = original length

deltaL= change in ...
