A uniform 1200 N beam that is 3.50 m long is suspended horizontally by two vertical wires at its ends. A small but dense 550 N weight is placed on the beam 2.00 m from one end, as shown in the figure. The tensions, A and B, in the two wires are: OA 8190 N, B = 8960 N = OA 836 N, B = 914 N OA 875 N, B = 875 N = OA 914 N, B = 836 N OA=8960 N, B = 8190 N B 2.00 m 3.50 m

8₁ 02 9. The diagram of the leg shows the femur (1) and tibia (2). The quadriceps muscle (3) applies a force to the lower leg via a tendon (4) that is embedded with the kneecap (5). If the force applied by the muscle to the tendon is F 570 N, what is the force of the femur on the kneecap, if the leg is in equilibrium? A simplified model of the leg is shown next to the diagram. The leg bones are represented by two beams attached by a pin. The tendon is modelled by a rope and the kneecap acts like a pulley. The tendon above the kneecap makes an angle 8, = 38° with respect to the vertical, and the portion of the tendon below the kneecap makes an angle of 6₂ = 10° with respect to the vertical. Enter the x component, followed by the y component. Answer 1 of 2: Answer 2 of 2: Submit All Answers

A hungry bear weighing 730 N walks out on a beam in an attempt to retrieve a basket of goodies hanging at the end of the beam (see the figure below). The beam is uniform, weighs 200 N, and is 7.00 m long, and it is supported by a wire at an angle of θ = 60.0°. The basket weighs 80.0 N. A horizontal plank is attached at the left end to a vertical wall. A rod with a pulley at the right end extends a distance x horizontally to the right from the wall above the plank. A cable connected to the wall just above the rod goes around the pulley then down and right to the end of the plank, making an acute angle θ with the plank. A basket of goodies hangs down from the right end of the plank and a bear stands on the plank below the rod a distance x from the wall. (a) Draw a force diagram for the beam. (Submit a file with a maximum size of 1 MB.)  This answer has not been graded yet. (b) When the bear is at  x = 1.10 m,  find the tension in the wire supporting the beam. NWhen the bear is at  x…

A car is stuck in the mud. A tow truck pulls on the car with the arrangement shown. The tow cable is under a tension of 2 500 N and pulls downward and to the left on the pin at its upper end. The light pin is held in equilibrium by forces exerted by the two bars A and B. Each bar is a strut; that is, each is a bar whose weight is small compared to the forces it exerts and which exerts forces only through hinge pins at its ends. Each strut exerts a force directed parallel to its length. Determine the force of tensionor compression in each strut. Proceed as follows. Make a guess as to which way (pushing or pulling) each force acts on the top pin. Draw a free-body diagram of the pin. Use the condition for equilibrium of the pin to translate the free-body diagram into equations. From the equations calculate the forces exerted by struts A and B. If you obtain a positive answer, you correctly guessed the direction of the force. A negative answer means that the direction should be reversed,…

A uniform 1200 N beam that is 3.50 m long is suspended horizontally by two vertical wires at its ends. A small but dense 550 N weight is placed on the beam 2.00 m from one end, as shown in the figure. The tensions, A and B, in the two wires are: B 2.00 m - 3.50 m A A = 914 N, B = 836 N (B) A = 8190 N, B = 8960 N A = 836 N, B = 914 N A = 8960 N, B = 8190 N
