Subject and UNIT: Engineering Mechanics: Unit IV: Friction

Solved Example Problems, Examples for Practice: Dry Friction - Friction - Engineering Mechanics

Solved Example Problems

Subject and UNIT: Engineering Mechanics: Unit IV: Friction

Problems involving dry friction can be broadly classified into two types.

Subject and UNIT: Engineering Mechanics: Unit IV: Friction

The normal reaction N and the frictional force Fr can be combined to give a resultant R called the resultant reaction as shown in Fig. 8.5.1.

Subject and UNIT: Engineering Mechanics: Unit IV: Friction

The force of kinetic friction opposes the relative motion between two surfaces in contact.

Subject and UNIT: Engineering Mechanics: Unit IV: Friction

Under static conditions, the friction force opposes tendency for relative motion between the two surfaces in contact and acts tangential to the surfaces.

Subject and UNIT: Engineering Mechanics: Unit IV: Friction

The normal reaction N and the frictional force Fr can be confined to give a resultant R called the resultant reaction as shown in Fig. 8.5.1.

Subject and UNIT: Engineering Mechanics: Unit IV: Friction

The force of kinetic friction opposes the relative motion between two surfaces in contact.
