    Answer:

    3.33×10⁸ Pa

    Explanation:

    Pressure: This can be defined as the force acting normally (perpendicular) per unit area. The S.I unit of force is N/m² or Pa.

    P = F/A……………… Equation 1

    Where F = force created with the tooth, A = Area.

    Given: F = 360 N, A = 1.08 mm² = 1.08/1000000 = 1.08×10⁻⁶m.

    Substitute this values into equation 1

    P = 360/1.08×10⁻⁶

    P = 3.33×10⁸ Pa.

    Hence the pressure created = 3.33×10⁸ Pa
