Question

The chewing muscle, the masseter, is one of the strongest in the human body. It is
attached to the mandible (lower jawbone) as shown in Figure P8.33a. The jawbone is
pivoted about a socket just in front of the auditory canal. The forces acting on the jawbone
are equivalent to those acting on the curved bar in Figure P8.33b.

Fc is the force exerted by the
food being chewed against the jawbone, T is the force of tension in the
masseter, and R is the force exerted by the socket on the mandible. Find
T and R for a person who bites down on a piece of steak with a force of
50.0 N.
