Understanding Reaction Forces on a Hinged Pulley under Tangential Force

Click For Summary
SUMMARY

The discussion focuses on the reaction forces experienced by a hinged pulley subjected to a tangential force. It is established that there will be a reaction force at the center of gravity of the pulley, but its magnitude will not necessarily equal the applied force. The net force at the center will depend on the magnitudes of forces P1 and P2 applied from both sides, which may differ. Additionally, the mass and moment of inertia of the pulley significantly influence the overall force dynamics.

PREREQUISITES
  • Understanding of basic mechanics, specifically forces and moments.
  • Knowledge of pulley systems and their configurations.
  • Familiarity with concepts of center of gravity and moment of inertia.
  • Basic principles of static equilibrium in physics.
NEXT STEPS
  • Study the effects of moment of inertia on pulley systems.
  • Learn about static equilibrium and its applications in mechanical systems.
  • Explore the dynamics of forces in pulley systems with varying mass distributions.
  • Investigate the mathematical modeling of forces in hinged mechanisms.
USEFUL FOR

Mechanical engineers, physics students, and anyone involved in the design and analysis of pulley systems and mechanical forces.

A tangential force is appliied on pully hinged at its centre of gravity. will there be any reaction force at its center?? if yes then how much? will it be same as applies force? practically it seems there would be no force at its center??
and if force is applied from the both side say P1 and P2, both are in same direction and not same in magnitude then what will be the net force applied at its center??

You have to give us a bit more detail. Are you assuming that the pulley is massless? Or does it have a non-zero moment of inertia? What is pulling the rope? What is on the other end of the rope? All these will affect whether and how much force is applied to the pulley.

Welcome to PF by the way!
