A Blue Elgiloy wire with a Young's modulus of Y = 1.6 × 10¹¹ Pa is used to press a tooth for correction of position. The wire is 3 cm long, has a diameter of 0.2 mm, bends under an angle of 140° where it presses the tooth, and stretches by 0.08 mm. What is the force exerted on the tooth? Assume that that tooth width is negligible so that the wire bends making an angle 140°.
