Question

Seems like no one I asked can get this question right.

                    Referring to the diagram in the figure(Figure 2) , where d = 7.70cm                     and D = 10.70cm                     , find the torque produced about the axis of rotation by the masseter muscle. The force exerted by the masseter muscle is FM = 500N . Assume                     that the mandible is in static equilibrium.
                

                    
                

Seems like no one I asked can get this question right. Referring to the diagram in the figure(Figure 2) , where d = 7.70cm and D = 10.70cm , find the torque produced about the axis of rotation by the masseter muscle. The force exerted by the masseter muscle is FM = 500N . Assume that the mandible is in static equilibrium.

Explanation / Answer

FM = 500N

Torque exerted by FM

= 500 cos26 * 3 * 10-2

= 13.48 Nm = 13.5 N.m
