A simple system of two masses and two pulleys

Click For Summary
SUMMARY

The discussion centers on calculating the acceleration of a system involving two masses and two pulleys. User Adam expresses confusion over differing answers he obtained while attempting to solve the problem. A key point raised is the incorrect assumption that the accelerations of the two masses (a1 and a2) are equal, which is clarified by the constraint imposed by the constant length of the rope attached to mass M2. This constraint is crucial for deriving the correct relationship between the accelerations.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Familiarity with pulley systems and constraints
  • Basic knowledge of kinematics and acceleration
  • Ability to set up and solve equations involving multiple variables
NEXT STEPS
  • Study the principles of pulley mechanics in classical mechanics
  • Learn how to derive equations of motion for systems with constraints
  • Explore the concept of tension in ropes and its effects on acceleration
  • Practice solving problems involving multiple masses and pulleys
USEFUL FOR

Students of physics, educators teaching mechanics, and anyone interested in understanding the dynamics of pulley systems and mass interactions.

A simple system of mass
Relevant Equations
mainly newtons second law
hey there,

I am confusing what is the right answer to this system of mass, I solved it a couple of time and I got different answers. can you help me with that?
I need to find the expression of the acceleration of the 2 masses.

thanks a lot,Adam.

on the left middle; if the system was stretch all the way. it will be easier to find the length equation, thanks a lot/

I see you somehow got that a1=a2. That is incorrect.

Consider that the rope attached to M2 is of constant length. That places a constraint on the relationship between a1 and a2.
