Question

Humans can bite with a force of approximately 810 n. if a human tooth has the young's modulus of bone, a cross-sectional area of 1.1 cm2, and is 1.6 cm long, determine the change in the tooth's length during an 8.10 ✕ 102 n bite. 7.36e-6 incorrect: your answer is incorrect. your response differs from the correct answer by more than 10%. double check your calculations. m

Answer 1

The pressure created by biting with a force of 500 N on a 1.00 mm² tooth area is calculated as 500 N divided by the area in square meters, yielding a result of 5.00 x 10⁸ pascals.

Step-by-step explanation:

The question is about calculating the pressure exerted by a human tooth during a bite. Pressure is defined as the force applied per unit area and is calculated using the formula pressure = force / area. To find the pressure in pascals when a force of 500 N is exerted on a tooth with a cross-sectional area of 1.00 mm² (or 1.00 x 10-6 m²), we use this formula: pressure = 500 N / 1.00 x 10-6 m². This results in a pressure of 5.00 x 108 pascals. When considering human capabilities, we must keep in mind that the values obtained in these calculations are ideal and actual values may vary due to biological and practical considerations.
