A wooden door 2.1 m high and 0.90 m wide is hung by two hinges 1.8 m apart. The lower hinge is 15 cm above the bottom of the door. The center of mass of the door is at its geometric center, and the weight of the door is 260 N, which is supported equally by both hinges. Find the horizontal force exerted by each hinge on the door.
In order to get his car out of the mud, a man ties one end of a rope to the front bumper and the other end to a tee 15 m away as shown below. He then pulls on the center of the rope with a force of 400 N, which causes its center to be displaced 0.30 m, as shown. What is the force of the rope on the car?
A stepladder of negligible weight is constructed as shown in Figure P10.73, with AC = BC = ℓ. A painter of mass m stands on the ladder a distance d from the bottom. Assuming the floor is frictionless, find (a) the tension in the horizontal bar DE connecting the two halves of the ladder, (b) the normal forces at A and B, and (c) the components of the reaction force at the single hinge C that the left half of the ladder exerts on the right half. Suggestion: Treat the ladder as a single object, but also treat each half of the ladder separately. Figure P10.73 Problems 73 and 74.
A stepladder of negligible weight is constructed as shown in Figure P10.73, with AC = BC = = 4.00 m. A painter of mass m = 70.0 kg stands on the ladder d = 3.00 m from the bottom. Assuming the floor is frictionless, find (a) the tension in the horizontal bar DE connecting the two halves of the ladder, (b) the normal forces at A and B, and (c) the components of the reaction force at the single hinge C that the left half of the ladder exerts on the right half. Suggestion: Treat the ladder as a single object, but also treat each half of the ladder separately.
A person carries a plank of wood 2.00 m long with one hand pushing down on it at one end with a force F1 and the other hand holding it up at .500 m from the end of the plank with force F2. If the plank has a mass of 20.0 kg and its center of gravity is at the middle of the plank, what are the magnitudes of the forces F1 and F2?
A bridge of length 50.0 m and mass 8.00 104 kg is supported on a smooth pier at each end as shown in Figure P12.25. A truck of mass 3.00 104 kg is located 15.0 m from one end. What are the forces on the bridge at the points of support? Figure P12.25
A uniform plank 8.00 m in length with mass 65.0 kg is supported at two points located 1.00 m and 5.00 m, respectively, from the left-hand end. What is the maximum additional mass you could place on the right-hand end of the plank and have the plank still be at rest?
At the gym, you notice a girl doing a “plank.” In this exercise, she holds the position shownwithout moving. You approximate she supports four-tenths of her weight on each arm. Out of curiosity,you want to calculate the change in length of her arm due to compression by her body weight. Assumeshe weighs 52 kg, her arm is 30. cm long prior to the plank, and her arm is 5.0 cm in diameter. Yourealize that it is actually the bone that is supporting her weight, rather than the muscles and othertissues that make up the rest of her arm, so you guess the humerus is the main bone involved with thesame initial length as the arm and an average radius of 2.5 cm. If Young’s modulus for bone undercompression is 22 GPa, how much does the bone compress?
A uniform log of length L is incline 30 ͦ from the horizontal when supported by a frictionless rock located 0.6Lfrom its left end. The mass of the log is 200 kg. an engineer with a mass of 53.5 kg walks along the log from theleft to the right until the log is balanced horizontally. How far from the left end of the log is the engineer when thelog is horizontal?
A horizontal plank 4.00 m long and having mass 20.0 kg restson two supports, one at the left end of the plank and a second1.00 m from the right end of the plank. What is the magnitude of theforce exerted on the plank by the support on the right side?
The bones of the forearm (radius and ulna) are hinged to the humerus at the elbow. The biceps muscle connects to the bones of the forearm about 2.15 cm beyond the joint. ,Biceps muscle Assume the forearm has a mass of 2.35 kg and a length of 0.445 m. When the humerus and the biceps are nearly vertical and the forearm is horizontal, if a person wishes to Humerus- hold an object of mass 5.75 kg so that her forearm remains motionless, what is the force exerted by the biceps muscle?

Hi, I am in physics I and I'm trying to understand this word problem. It saids that a 6.0-m uniform board is supported by two sawhorses 4.0m apart. A 32kg child walks on the board to 1.4 m beyond the right support when the board start to tip. a.) Find the mass of the board b.) Then he walks back 0.40m and stands still. Find the forces exerted by the supports at this time. (use the mass found in part a). Please be detailed of how this works. Its a harder problem for me to understand. Thank you!
