Answer:
τ = 0.009 Nm
Step-by-step explanation:
The torque applied on the tooth can be given by the following formula:
![\tau = Fd](https://img.qammunity.org/2021/formulas/physics/college/keo44b2mdbqdvrzdofjoos98jsx7rmbqkg.png)
where,
τ = Torque on the tooth= ?
F = Force acting on tooth = 9 N
d = distance between force and tooth axis = 1 mm = 0.001 m
Therefore, using these values in the equation, we get:
![\tau = (9\ N)(0.001\ m)](https://img.qammunity.org/2021/formulas/physics/college/76bi53gkr0om47b9lvujk04ftstni94dlt.png)
τ = 0.009 Nm
