SUMMARY

The discussion focuses on the torque requirements for rotating wheels without skid. It establishes that to initiate rotation, the applied torque must overcome the static friction moment at the contact point. Once rotation begins, the torque must decrease to maintain the necessary tangential force to prevent skid. It concludes that there will always be a minimum skid at the start of rotation, as static friction adjusts to prevent relative motion between the wheels.

PREREQUISITES
  • Understanding of static friction and its role in motion
  • Basic knowledge of torque and its application in rotational dynamics
  • Familiarity with the concepts of tangential force and acceleration
  • Knowledge of wheel dynamics and contact mechanics
NEXT STEPS
  • Research the principles of static friction and its limits in mechanical systems
  • Study torque calculations in rotational motion using Newton's laws
  • Explore the relationship between tangential force and wheel slip in vehicle dynamics
  • Learn about the effects of varying torque on wheel performance in different conditions
USEFUL FOR

Mechanical engineers, automotive engineers, physics students, and anyone involved in the design or analysis of rotating systems and vehicle dynamics.

If I have two wheels with a contact point connection when the one of the wheels is starting a rotation due to a certain torque which condition do the torque have to fulfill in order to:
1) starting the rotation
2) guarantee a rotation without skid

My toughs for now are:
1) the torque has to face the static friction moment acting on the contact point. This is just to start the rotation.
2) after the initial rotation the torque can has to decrease in order to transmit the right tangential force for assure no skid.
Result (for me): there always be a minimum skid at the rotation starts.

Please answer me because this is killing me :nb):nb):nb):nb)

The force of static friction will take on whatever value it has to (within its limits) in order to prevent relative motion between the two wheels. If the wheels are at rest and under no external torques than the force of static friction will be zero. There is nothing to overcome.

If any torque is applied to the one wheel, no matter how small, the static friction will adjust itself so that the two wheels accelerate smoothly together.
