Maximum force pulling a wheel without it slipping

Click For Summary
SUMMARY

The discussion focuses on calculating the maximum force that can be applied to a wheel without slipping, given a mass of 1.5 kg, a radius of 0.06 m, and a static friction coefficient of 0.3. The maximum static friction is determined to be 4.5 Newtons. To accurately calculate the force, the relationship between torque and the moment of inertia must be established, particularly for a uniform disk. The moment of inertia can be derived from the wheel's characteristics if not provided in the problem statement.

PREREQUISITES
  • Understanding of static friction and its calculation
  • Knowledge of torque and its formula (M = radius x force)
  • Familiarity with moment of inertia, particularly for a uniform disk
  • Basic principles of rotational and translational motion
NEXT STEPS
  • Research the moment of inertia for various shapes, focusing on the solid cylinder
  • Learn about the relationship between torque and angular acceleration
  • Study the principles of rotational dynamics and their application in real-world scenarios
  • Explore advanced friction concepts, including kinetic friction and its effects on motion
USEFUL FOR

This discussion is beneficial for physics students, mechanical engineers, and anyone involved in the study of dynamics and rotational motion, particularly in applications involving wheels and friction.

Homework Statement


We have a wheel with [mass = 1.5 kg] and a [radius = 0.06 m]. The static friction thing between the ground and the wheel is 0.3 . WIth how much force can we pull the string spooled around the wheel without the wheel slipping. The string ends at the top of the wheel and we pull it parallel to the ground.

Homework Equations


Torque, M = radius x force.
Maximum static friction, mass * g * 0.3.

The Attempt at a Solution


The maximum static friction between the ground and the wheel is 4.5 Newtons. I do not know how to factor in torque.

Maybe you specify the relationship between rotational and translational motion.
 
As azizlwl says it depends on that relationship. To use the relationship you need the moment of inertia of the wheel. Did they give you that in the problem? If not, you can work it out if they give you the characteristics of the wheel. The simplest assumption is that it's a uniform disk, for which the moment of inertia can be found on this page under 'solid cylinder'.
