1. Use Newton’s laws since we are looking for forces.
2. Draw a free-body diagram:
Figure 4.29.
3. The tension is given as Find Using Newton’s laws gives: so that applied force is due to the y-components of the two tensions:
The x-components of the tension cancel. .
4. This seems reasonable, since the applied tensions should be greater than the force applied to the tooth.
