What is meant by lubrication ? Why do we lubricate the moving parts of our vehicles ? Name some lubricants and where they are used

Lubrication is the process of reducing friction between two surfaces that are in contact with each other. This is achieved by introducing a substance known as a lubricant between the surfaces to minimize direct contact, and hence, reduce wear and tear, and heat generation.

We lubricate the moving parts of our vehicles to reduce the friction between them. This is important because friction can cause wear and tear of the parts, leading to their damage and eventual failure. Additionally, friction generates heat, which can cause overheating of the parts and lead to their degradation or even melting. By lubricating these parts, we can enhance their lifespan and maintain the efficiency of the vehicle.

Some common lubricants include:

• Motor Oil: This is used in the engines of vehicles to lubricate the moving parts such as the pistons, crankshaft, and camshaft.

• Grease: This is a semi-solid lubricant used in various parts of a vehicle, including wheel bearings and chassis, to protect against rust and corrosion.

• Transmission Fluid: This is used in the transmission of vehicles to lubricate the gears and prevent overheating.

• Brake Fluid: This is used in the brake system of vehicles to reduce friction and ensure smooth operation of the brakes.

• Gear Oil: This is used in the gearboxes of vehicles to lubricate the gears and ensure their smooth operation.
