A stainless steel orthodontic wire is applied to a tooth, as shown in the figure above. The wire has an unstretched length of 2.7 cm and a diameter of 0.2 mm. The wire is stretched 0.1 mm. Young's modulus for stainless steel is 1.80E+11 Pa.
1. What is the tension in the wire?
2. What is the magnitude of the force on the tooth due to the wires? Disregard the width of the tooth.
