Magnitude and direction of tension in a suspended and frictionless pulley

Click For Summary
SUMMARY

The discussion focuses on analyzing the magnitude and direction of tension in a suspended and frictionless pulley system. Participants emphasize that the system is in equilibrium, leading to the conclusion that the sum of the vertical forces (Ʃfy) and the sum of the horizontal forces (Ʃfx) equal zero. By resolving the forces into their components and applying these equilibrium equations, users can accurately determine the tension in the system.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Basic knowledge of equilibrium in physics
  • Familiarity with vector resolution of forces
  • Concept of tension in strings and pulleys
NEXT STEPS
  • Study the principles of static equilibrium in physics
  • Learn about vector resolution techniques for force analysis
  • Explore real-world applications of pulleys in mechanical systems
  • Investigate the effects of friction in pulley systems
USEFUL FOR

Physics students, mechanical engineers, and anyone interested in understanding the dynamics of pulley systems and tension analysis.

The masses are suspended, therefore you can assume the system is in equilibrium, and all of the component forces = 0. Form an equation (or 2) for this.
 
How?
 
Ʃfy = 0
Ʃfx = 0

There are your 2 statements, resolve the forces you have into component forces, apply the statements above, and you will get the correct answer.
