Atwood Machine simulation problem

In summary, the Atwood Machine simulation involves two masses, m1 and m2, with m2 resting on the floor and experiencing a normal force, Fn. At equilibrium, the tension in the rope at 2.54s is 9.789. Using the equations F_n + T - m2*g = 0 and T - m1*g = 0, we can determine that the normal force is equal to 1.0 N. This information is based on the question of what normal force does the floor exert on m2 when m2 rests on the floor, with a timed simulation at 2.54s.

Need a check on this one please. In an Atwood Machine simulation, m1 is 1.0kg and m2 is 1.1kg. m2 rests on the floor that exerts a normal force, Fn, on m2. when the system is in equalibrium, the tension, T, in the rope at 2.54s is 9.789. If Fn +T- m2*g = 0 then Fn = .991. Is this correct?

If the question is "What normal force does the floor exert on m2 when m2 rests on the floor?" then you're probably OK. (Although I have no idea what 2.54s has to do with anything.)

The forces on m2 are: [itex]F_n + T - m_2 g = 0[/itex]; similarly, the forces on m1 are: [itex]T - m_1 g = 0[/itex]. So [itex]F_n = (m_2 - m_1)g[/itex].

The question "What is the normal force, FN, and what is the tension, T, in the rope? T (at t = 2.54s) = ______. At equilibrium: FN + T – m2 • g = 0. Then FN = _______." This is a timed simulation and at 2.54s the rope tension,T, is 9.789

OK, now I see what you're talking about. Since T is given and equilibrium is assumed, your answer is correct; rounded off, the normal force would be 1.0 N.

Thanks for the quick reply.
 

1. What is an Atwood Machine simulation problem?

An Atwood Machine simulation problem is a physics problem that involves using a virtual simulation or model to analyze the motion of a system made up of two masses connected by a string passing over a pulley. The simulation allows for the manipulation of parameters such as mass, acceleration, and velocity to observe the effects on the motion of the system.

2. How does an Atwood Machine simulation problem relate to real life?

An Atwood Machine simulation problem relates to real life in the sense that it is a simplified representation of a real-world physical system. It helps us understand concepts such as gravity, mass, and acceleration, and how they affect the motion of objects. The simulation can also be used to solve real-world problems, such as determining the force needed to lift an object or the speed at which an object will fall.

3. What are the benefits of using an Atwood Machine simulation?

One of the main benefits of using an Atwood Machine simulation is that it allows for a visual representation of a physical system, making it easier to understand and manipulate. It also allows for the testing of different scenarios and parameters without the need for physical equipment, saving time and resources. Additionally, simulations can provide more accurate results than experiments, as they eliminate human error.

4. What are some common applications of Atwood Machine simulations?

Atwood Machine simulations have various applications in physics and engineering. They are commonly used to study the motion of objects in free fall, analyze the forces acting on a system, and determine the acceleration of objects. They are also used in the design and testing of machines and structures, such as elevators and cranes, to ensure their safety and efficiency.

5. Are there any limitations to Atwood Machine simulations?

While Atwood Machine simulations have many advantages, they also have limitations. One of the main limitations is that they are simplified models and may not accurately represent real-world scenarios. Additionally, simulations rely on mathematical equations and assumptions, which may not always reflect the complexity of a real-life situation. It is important to use simulations in conjunction with experiments to validate the results and gain a more comprehensive understanding of a system.
