14. BIO A stainless-steel orthodontic wire is applied to a
tooth, as in Figure P9.14. The wire has an unstretched
length of 3.1 cm and a radius of 0.11 mm. If the wire is
stretched 0.10 mm, find the magnitude and direction
of the force on the tooth. Disregard the width of the
tooth and assume Young's modulus for stainless steel is
18 X 100 Pa.
