The chewing muscle, the masseter, is one of the strongest in the human body. It is attached to the mandible (lower jawbone) as s

hown in figure
(A) 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
(B) In figure a, a skull is shown. The lower jaw is labeled "Mandible".
A muscle labeled "Masseter" connects the back of the lower jaw to the upper part of the skull. In figure b, The jawbone is modeled by a curved bar. The left portion of the bar is horizontal, the right portion bends diagonally up and to the right. Three forces act on the bar: Vector T points directly upward at the point where the bar bends. Vector FC acts directly downward at the left end of the bar, a horizontal distance of 7.50 cm from vector T. Vector T points directly upward at the point where the bar bends. Vector R acts directly downward at the right end of the bar, a horizontal distance of 3.50 cm from vector T. F C 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 (in N) for a person who bites down on a piece of steak with a force of 56.6 N. magnitude of R N

What does the diameter in meters need to be of a round parachute that the designer has determined needs to have an area of 500 s
Marrrta [24]
Area of a circle is
A= pi r^2
so
500m^2 = 3.14 r2
500/pi = r ^2
152.1549...=r^2
square root both sides
r=12.61566...
d=2r
d=25.2

pychu [463]

The global warming is the uniform heating of the globe due to the effect of greenhouse gases.

Answer: Option B

<u>Explanation:</u>
