An Atwood machine consists of two blocks (of masses m_1 and m_2) tied together with a massless rope that passes over a fixed, perfect (massless and frictionless) pulley. For all parts of this problem, take upward to be the positive direction and take the gravitational constant, g, to be...

Homework Statement A simple pulley has two masses on either end, one M1 and one M2. It is easy to find the acceleration of the two masses, and the tension on the rope suspending these masses. The pulley is suspended by a cord, however, and the question asks to find the tension in this cord...

help! atwood machine The two masses in the Atwood's machine shown in the figure below are initially at rest at the same height. After they are released, the large mass, m2, falls through a height h and hits the floor, and the small mass, m1, rises through a height h. In this Atwood's...

Homework Statement Simple question I'm sure, but I want clarification if possible. If you do an experiment with the Atwood machine and you need to calculate 'g', should it be close to 9.8 m/s^2 ? Homework Equations No equations necessary, theoretical question. I would think the Atwood...

I am in high school, taking a college Physics for Scientists and Engineers class. I am stuck on one problem concerning an atwood device. I have an atwood device with two masses (m1<m2, m2 higher than m1, connected via a massless string) and a pulley with a mass Mp and radius Rp. The pulley...

I was working on my physics homework and I came across a question that I couldn't find an example of in my notes. I'm not sure which formulas I need to use and in which order to use them. Here's the question: Two objects with masses of 3.00 kg and 5.00 kg are connected by a light...

With an Atwood Machine, I understand that the formula for calculating T can be calculated with two simultaneous equations. T-m1g=m1a a= (m2 - m1 ( T – m1

im stuck on the last question of this lab. "what combination or masses would make the accelration of an atwood machine equal to 1/2 g?" a = g (m1 - m2/m1=m2) so i have to find out what m1 and m2 are eual to in that forumula if g = 1/2 im thinking a is equal to 9.81 because the...

Here’s a question for you all… but first some background (see jpeg attachment for sketch) Assuming all surfaces are frictionless (5kg on horizontal surface, two 2kg blocks on 5kg block), and the pulley has no mass, with what horizontal force applied to the 5kg block will the two 2kg...

An atwood machine holds two masses at its ends by a massless rope. m1 and m2. Assume the pully is frictionless. What will the magnitude of the tension(T) go to as m1 goes to infinity but m2 stays the same? Im very lost on this problem. I have drawn a free body diagram showing m1g and m2g...

I have been working on this problem off-and-on for a couple of days now and cannot seem to get the correct answer. The problem is an Atwood machine problem. The following are the variables: Mass of pulley = .20 kg Radius of pulley = .15 m Clockwise frictional torque = .35 m*N Mass 1 on...

In the Atwood machine regular 2 mass machine,m1= 2.20kg and m2=7.30kg . The masses of the pulley and string are negligible by comparison. The pulley turns without friction and the string does not stretch. The lighter object is released with a sharp push that sets it into motion at an initial...

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?

I was given this problem below in my physics homework. :cry: http://www.turbozcar.com/images/knight.Figure.08.40.jpg It wants to know the acceleration of m1. I couldn't figure it out, so the next day a friend in class gave me the answer to be: (2*m_2*g)/(4*m_1+m_2) I took that...

Need closure (if not guidance) on this problem also: An Atwood machine consists of two masses, m_1 and m_2, which are connected by a massless inelastic cord that passes over a pulley. If the puley has radius r and moment of inertia I about its axle, determine the acceleration of the masses...

There is a problem in my physcs book that I have been trying to solve for some time now, and I just can't get trough it. If someone could help me a little bit, it would really be great. My question is about the Atwood machine. There are two blocks of same weight (M) suspended on a rope of...
