Will a Massless Pulley with Friction Rotate with Unequal Masses on Either Side?

Click For Summary
SUMMARY

A massless pulley with friction will indeed rotate when two unequal masses are connected to it on either side. The friction between the pulley surface and the string plays a crucial role in the system's dynamics. The heavier mass will exert a greater force, causing the pulley to rotate in the direction of the heavier side. This conclusion is based on the principles of classical mechanics and the behavior of pulleys in systems with unequal forces.

PREREQUISITES
  • Understanding of classical mechanics principles
  • Knowledge of pulley systems and their functions
  • Familiarity with the concept of friction in mechanical systems
  • Basic grasp of forces and mass interactions
NEXT STEPS
  • Study the effects of friction on pulley systems in detail
  • Explore the equations of motion for systems with unequal masses
  • Learn about torque and its application in rotating systems
  • Investigate real-world applications of pulleys in engineering
USEFUL FOR

Physics students, mechanical engineers, and anyone interested in the dynamics of pulley systems and frictional forces.

a massless pulley with friction between its surface and the string passing over it .If string is having two unequal masses connected to it on both side of pulley then will the pulley rotate?

If this is what you mean, yes it will rotate.
