Engine Friction and Lubrication

Tribology is derived from the greek word “tribos”, which means?

In 1493, He made significant observations about friction and lubrication, including the concept of reducing friction by using a layer of lubricant between moving surfaces.

• Leonardo da Vinci

• Guillaume Amontons

• Peter Jost

• Richard Stribeck

He formulated the empirical laws of friction, which established the relationship between frictional force and applied load or contact area.

• Leonardo da Vinci

• Guillaume Amontons

• J.W. Lund

• Richard Stribeck

Who coined the term "tribology" in a report commissioned by the British government, highlighting the economic and industrial importance of understanding friction, wear, and lubrication.

• Leonardo da Vinci

• Guillaume Amontons

• Peter Jost

• Richard Stribeck

Developed the concept of the ball bearing, which revolutionized machinery design by reducing friction and enabling smooth rotational motion.

• Leonardo da Vinci

• Richard Stribeck

• J.W. Lund

• Peter Jost

Presented a graphical representation of the relationship between friction, lubrication regime, and lubricant properties.

• Leonardo da Vinci

• J.W. Lund

• Peter Jost

• Richard Stribeck

Focuses on friction and wear in machine elements, rolling elements, bearings, gears, plain bearings, brakes, clutches, wheels, as well as manufacturing processes.

• Green Tribology

• Classical Tribology

• Geotribology

• Biotribology

The force that resists motion when the surface of one object comes in contact with the surface of another.

The gradual removal, damaging or displacement of material at solid surfaces.

Occurs when a hard, rough surface slides across a softer surface.

• Abrasive Wear

• Adhesive Wear

• Fretting Wear

• Erosive Wear
