Outside of a diner you notice a precarious 10 kg sign hanging above the entrance, supported by a 12 kg, 0.9 m long support beam. The beam is attached to the sign at one end, and a cable two-thirds of the way along the beam. 1. Draw a complete rigid body diagram for the support beam. 2. Determine the tension in the cable and the magnitude of force at the wall.

The mass of the rope acts on its center of mass. In the same way, gravitational force also acts upward. If the tension force will not contain any vertical components, the net force brings about a upward acceleration for the rope B. The mass of the rope acts on its center of mass.

The chewing muscle, the masseter, is one of the strongest in the human body. It is attached to the mandible (lower jawbone). 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 as shown in the figure. ?C is the force exerted against the jawbone by the food being chewed, ?T is the tension in the masseter, and ?R is the force exerted on the mandible by the socket. Find (a) ?T and (b) ?R if you bite down on a piece of steak with a force of 50.6 N. Neglect the weight of the jawbone. (a)T. (b)R.
Scientists have studied how snakes grip and climb ropes. In one study, they found that an important characteristic of a rope is its “compliance”— that is, how easily the rope, while under tension, can be flexed. As shown how scientists measured a rope’s compliance by attaching it to two strings, each supporting an identical mass m. The strings contort the rope so that its middle section lies at angle θ. For θ = 30° and m = 100 g, what are the tensions T1 and T2 in the upper and middle parts of the rope?
