- Bart ( whose mass is 31.1 kg) and Milhouse (whose mass is 20.4 kg) sit balanced on a teeter -totter that has its pivot point at its exact center . If the two boys are separated by a distance of 2.52 m, at what distance (in m) from the pivot point must Milhouse be sitting at in order to maintain the balance? Explain how you solved the problem involving children balancing on a teeter-totter. Be sure to state what your known and unknown quantities are, what concepts were applied, and what equations were used!Two children of mass 21 kg and 26 kg sit balanced on a seesaw with the pivot point located at the center of the seesaw. If the children are separated by a distance of 2 m, at what distance from the pivot point is the small child sitting in order to maintain the balance? mA 7.1 N weight is attached 5.0 cm from the fulcrum of a balance beam. What weight should be placed 1.4 cm away from the fulcrum on the other side of the beam in order to balance the system?
- A meter stick balances horizontally on a knife-edge at the 50.0 cm mark. With two 6.35 g coins stacked over the 11.5 cm mark, the stick is found to balance at the 43.4 cm mark. What is the mass of the meter stick?Two kids are on a uniform seesaw supported at its center. The kid is on the right side of the seesaw has a mass m kg and is at a distance 1.59 from the center of the seesaw. The kid is on the left side of the seesaw has a mass 30.8 kg and is at a distance 1.49 from the center of the seesaw. The seesaw is in static equilibrium. What is the mass m in kg? Give your answer to three significant figures.The uniform seesaw shown below is balanced on a fulcrum located d1 = 3.5m from the left end. The bigger boy on the left end has a mass m1 =75 kg. The smaller boy on the right end has a mass of m2 = 55 kg and is a distance d2 = 4.5 m from the fulcrum. The mass of the board is mb. Draw all forces acting on the seesaw board showing their directions and locations. Where would you draw the weight of the board? Identify and show the direction of rotations caused by the torques provided by all forces about the fulcrum. If the seesaw is in static equilibrium, write down the two conditions of static equilibrium symbolically using the forces and distances in the figure. Solve for the mass of the board. Calculate the force of fulcrum on the board.
- A rider of mass 77.0-kg sits 1.60 meters left of the pivot point. A different rider sits 3.3 meters to the right of the pivot point. If the see-saw is in equilibrium, what is the rider on the right's mass? The mass of the see-saw is 18.9-kg Give your answer in kilograms to 3 significant figures (1 decimal place).Jack and Jill want to balance their seesaw. Where should they set the fulcrum? Jack has a mass of 25 kg, Jill has a mass of 15 kg, and the seesaw board has a mass of 20.0 kg.Bob and Anna sit on opposite ends of a uniform see-saw which is 12.0 m in length. The see-saw is balanced by a fulcrum which is located 4.00 m from Bob. Bob has a mass of 85.0 kg, and the see-saw itself has a mass of 100 kg. Anna’s mass is unknown. NOTE THAT THE FULCRUM IS NOT PLACED AT THE CENTER OF MASS OF THE SEE- SAW!!! a) What is the net torque on the see-saw? Explain clearly and briefly how you know. b) Draw a properly labeled extended force diagram of the see-saw c) Solve for Anna’s mass. Show your work clearly!
- A rider of mass 78.0-kg sits 1.70 meters left of the pivot point. A different rider sits 3.5 meters to the right of the pivot point. If the see-saw is in equilibrium, what is the rider on the right's mass? The mass of the see-saw is 19.2-kg Give your answer in kilograms to the correct number of significant figures.Scenario: A heavy kid and a light kid are at the two ends of a see-saw, modeled as a long thin rod with point masses at each end, pivoted at the middle. The see-saw is tilted from horizontal. See-saw end-to-end length: 4.5 meters See-saw mass: 15 kg Heavy kid's mass: 39 kg Light kid's mass: 25 kg Tilt angle: 14 degrees (a) What is the magnitude of the net torque on the see-saw due to gravity, in newton-meters? N m (b) What is the moment of inertia of the two-kid system about the pivot at the center of the see-saw? kg m2 (c) What is the magnitude of the see-saw's angular acceleration at this instant? rad/s?A wood plank (length 4.4 m and mass 13.0 kg) is balanced between two saw horses, as shown in the figure below. One saw horse is positioned directly under one end of the plank, and the other is located a distance d1 = 3.4 m away. A child (mass 25 kg) walks along the plank, as if it were a balance beam. What is the furthest distance d2 (in meters) from the end of the plank that the child can walk before the plank tips and falls? Hint: When the plank starts to tip, one of the forces becomes zero.
