Axles are shafts that rotate with the wheels and support the weight of the vehicle. They come in various types depending on the vehicle's design and purpose.

• Solid Axle: A single piece of metal that connects the wheels on either side of the vehicle.

• Independent Suspension Axle: Each wheel has its own axle, allowing for more flexibility and better handling.

• Drive Axle: Transfers power from the engine to the wheels, can be front, rear, or all-wheel drive.

• Dead Axle: Does not transm...read more

There are several types of bearings used in various industries, including ball bearings, roller bearings, plain bearings, and fluid bearings.

• Ball bearings are the most common type and consist of balls enclosed between inner and outer races to reduce friction.

• Roller bearings use cylindrical rollers instead of balls for higher load capacity and durability.

• Plain bearings have a simple design with a sliding surface to support rotating or sliding components.

• Fluid bearings use a th...read more

The steering system of a car is responsible for controlling the direction of the vehicle by allowing the driver to turn the wheels.

• The steering wheel is connected to the steering column, which is connected to the steering gear.

• The steering gear then transfers the motion to the steering linkage, which connects to the wheels.

• There are different types of steering systems such as rack and pinion, recirculating ball, and power steering.

• Power steering systems use hydraulic or elect...read more

Heat treatment is a process used to alter the physical and mechanical properties of a material through controlled heating and cooling.

• Heat treatment involves heating the material to a specific temperature, holding it at that temperature for a certain amount of time, and then cooling it at a controlled rate.

• The purpose of heat treatment is to improve the material's hardness, strength, toughness, ductility, and other properties.

• Common types of heat treatment include annealing, ...read more
