Resultant force on a pulley system

Click For Summary
SUMMARY

The discussion focuses on calculating the resultant force's magnitude, direction, and couple in a pulley system, specifically the top (alternator) pulley. The angle of 30° significantly influences the equations used, as traditional notes typically address forces in parallel. The key equation involves the radius multiplied by the force, which is essential for determining the resultant force. The system operates at a constant speed, indicating that dynamic equilibrium principles apply.

PREREQUISITES
  • Understanding of basic physics concepts related to forces and pulleys
  • Familiarity with trigonometric functions, particularly how angles affect force calculations
  • Knowledge of dynamic equilibrium and its application in mechanical systems
  • Ability to apply the equation of torque, specifically radius times force
NEXT STEPS
  • Study the principles of static and dynamic equilibrium in mechanical systems
  • Learn how to apply trigonometric functions to resolve forces at angles
  • Research the concept of torque and its calculation in pulley systems
  • Explore examples of resultant force calculations in similar pulley configurations
USEFUL FOR

Students studying physics, particularly those focusing on mechanics, as well as engineers and technicians working with pulley systems and force analysis.

Homework Statement



Could anyone give me an idea of how to start this problem to work out the resultant force's magnitude, direction and couple in the top (alternator) pulley?

Does the 30° angle affect the equations? As all the notes I have seem to only have pulleys with the force at each side in parallel to one another other. Also the system is running at a constant speed.

Homework Equations



I believe the equation needed is radius times force but again I can't seem to find any notes on how to answer this question.

The Attempt at a Solution



How to start the question is what I'm asking help with

Thanks for any help!

Yes, the angle affects the resultant.
