Two children push on opposite sides of a door during play. Both push horizontally and perpendicular to the door. One child pushes with a force of 165 N at a distance of 0.400 m from the hinges, and the second pushes at a distance of 0.450 m. What force must the second exert to keep the door from moving? Assume friction is negligible.

Two Boy Scouts, Bobby and Jimmy, are carrying a uniform wooden tent pole 4.50 m in length and having mass m = 23.0 kg. Bobby is holding the pole 60.0 cm from the back, and Jimmy is holding the pole 40.0 cm from the front. If the pole is held horizontally by the two boys, what is the force Bobby and Jimmy each exert on the beam?
A cart and rider have a total mass of 56.8 kg. The cart is rolling down a hill and accelerating at 0.5g. The coefficients of kinetic friction and of rolling friction between the carts wheels and the road are 0.20 and 0.020 respectively. What is the angle of the hills slope measured upward from the horizontal? You may find a spreadsheet program helpful in answering this question.
A filled treasure chest (m = 375 kg) with a long rope tied around its center lies in the middle of a room. Dirk wishes to drag the chest, but there is friction between the chest and the floor with s = 0.52. If the angle between the rope and the floor is 30.0, what is the magnitude of the tension required to just get the chest moving?
In Problem 10, the mass of the sign is 25.4 kg, and the mass of the potted plant is 66.7 kg. a.

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.
