SUMMARY

The maximum angle at which a solid cylinder rolls without slipping on an inclined plane, given that a block of the same material begins to slide at an angle of 12.95°, can be determined using principles of friction and torque. The frictional force must counteract the component of gravitational force parallel to the incline. The condition for the cylinder to roll without slipping involves ensuring that the linear motion of the center of mass remains zero while the torque due to friction is balanced. The discussion emphasizes the need to derive expressions for both frictional force and torque for accurate calculations.

PREREQUISITES
  • Understanding of frictional forces in inclined planes
  • Knowledge of torque and its application to rolling objects

Homework Statement


A block of a certain material begins to slide on an inclined plane when the plane is inclined to an angle of 12.95°. If a solid cyclinder is fashioned from the same material, what will be the maximum angle at which it will roll without slipping on the plane?


Homework Equations





The Attempt at a Solution


I really don't know how to even start this problem. Any help will be appreciated. Thanks.

Since the block slides when the angle of of inclination θ, the surface is not frictionless.
So what is the expression of frictional force Fr?
If the block remains at rest on the inclined plane, what is the condition?
In the case of cylinder, linear motion of the center of mass must be zero and torque due to Fr should be zero. What is the expression of the torque on a cylinder?
What is the torque on the cylinder due to Fr?
