Find acceleration of a modified atwood machine

Click For Summary
SUMMARY

The discussion focuses on calculating the acceleration of a modified Atwood machine, which consists of a disk with a mass of 2.4 kg and a radius of 23.4 cm, under the influence of gravity at 9.8 m/s². Participants utilized the equations of motion, specifically the sum of forces (ΣF = ma) and torque (τ = Iα), to analyze the system. The approach involved converting masses to weights and determining the resultant moment about the disk. The calculations aimed to derive the system's acceleration based on the forces acting on the bodies involved.

PREREQUISITES
  • Understanding of Newton's second law (ΣF = ma)
  • Knowledge of rotational dynamics (torque = Iα)
  • Familiarity with the concept of moment of inertia (I)
  • Basic principles of mechanics related to Atwood machines
NEXT STEPS
  • Study the derivation of acceleration in Atwood machines using different mass configurations
  • Explore the calculation of moment of inertia for various shapes and bodies
  • Learn about the effects of friction on the acceleration of pulley systems
  • Investigate advanced dynamics simulations for complex mechanical systems
USEFUL FOR

Students in physics or engineering courses, educators teaching mechanics, and anyone interested in understanding the dynamics of pulley systems and Atwood machines.

Homework Equations


\sumF=ma
torque = I(alpha)

The Attempt at a Solution


i tried to find the sum of the forces in the y direction for the 3 different bodies, then i tried to find the torque for the pulley and use one of the bodies' force and set it equal to the torque

Convert all the masses to weights, then find the resultant moment about the disk (the resultant of 1.66 and 1.28). Then use Torque=I*alpha
