How to Calculate Masses and Acceleration in an Atwood Machine Problem

Click For Summary
SUMMARY

The Atwood Machine Problem involves calculating the mass required for equilibrium when one mass is 1.9 kg and the displacement of either mass is 0.1 m in the first second after release. Using the kinematic equation S = (1/2)at², where t = 1 sec, the required acceleration is determined. By applying Newton's second law (F = ma) for both masses and eliminating the tension in the string, the relationship between the two masses can be established to solve for the unknown mass.

PREREQUISITES
  • Understanding of Newton's second law (F = ma)
  • Familiarity with kinematic equations
  • Basic knowledge of the Atwood machine setup
  • Ability to manipulate algebraic equations
NEXT STEPS
  • Study the derivation of kinematic equations in physics
  • Learn about tension in strings and its role in pulley systems
  • Explore advanced problems involving Atwood machines
  • Investigate the effects of friction and mass of strings on acceleration
USEFUL FOR

Students in physics, educators teaching mechanics, and anyone interested in solving classical mechanics problems involving pulleys and acceleration.

Atwood Machine Problem please help :)

If one of the masses of an Atwood machine is 1.9 kg, what must be the other mass if the displacement of either mass is to be 0.1 m in the first second after release?

Assuming mass-less strings,etc,

Calculate the required acceleration to travel 0.1m in 1 sec from the Kinematic equation S=(1/2)at2 (here t=1 sec).

Now assuming tension in the string to be T,
Write equations of motion(F=ma) for both masses,and eliminate the tension to obtain your result
