The chewing muscle, the masseter, is one of the strongest in the human body. It isattached to the mandible (lower jawbone) as shown in Figure P8.33a. The jawbone ispivoted about a socket just in front of the auditory canal. The forces acting on the jawboneare equivalent to those acting on the curved bar in Figure P8.33b. Fc is the force exerted by thefood being chewed against the jawbone, T is the force of tension in themasseter, and R is the force exerted by the socket on the mandible. FindT and R for a person who bites down on a piece of steak with a force of50.0 N.Figure P8.3283.50 cm7.50 cmMasseterMandible
