A dental bracket exerts a horizontal force of 66.8 N on a tooth at point B in the figure. What is the torque on the root of the tooth about point A?(Leave answer in N*m counterclockwise)
Thank you for the opportunity to help you with your question!
The formula to calculate the torque on the root is :T = F X D
We are given a Force = 66.8 N ; distance (D): ? 2 m
So the torque would be to plug into the formula:
T = 66.8N X 2 m
= 133.6 N*m
Says its incorrect
What is the distance m?
Just plug into the formula. T = F X D
You did not have a picture for the distance from A to B. What is d?
