Rolling Motion When Force Acts On A Body|Rolling Motion On Inclined Plane

In this passage a brief idea is given of the motion of the rolling bodies on an inclined plane. We will consider three cases: objects are released on an incline plane Case-A: which is smooth. Case-B: where friction is insufficient to provide pure rolling. Case-C: where friction is sufficient to provide pure rolling. Force diagram for three cases are as follows: (where symbols have their usual meanings) We have four objects: a solid sphere, a hollow sphere, a ring and a disc, all of same radius. When these are released on an inclined plane, it may happen that all of them do not perform pure rolling. But from the information of pure rolling, if one object can be confirmed to be purely rolling then it can be said that rest all will perform pure rolling. This object whose pure rolling confirms pure rolling of all other objects is

Rolling motion:Introduction||Pure rolling examples||Kinematics OF rolling motion

A : rigid body can't be in a pure rolling on a rough inclined plane without giving any external force. R : Since there is no torque providing force acting on the body in the above case, the body can't come in a rolling condition.

Figure shows a yo-yo placed on a rough surface friction is sufficient for pure rolling. After force F acts pure rolling begins Statement-1: Angular acceleration of yo-yo is in clockwise sense. Statement-2: Torque due to F must be larger than the torque due to friction.
