Types of load taken by bearing include radial load, axial load, and combined load.
Radial load: Load acting perpendicular to the axis of rotation, like the weight of a rotating shaft.
Axial load: Load acting parallel to the axis of rotation, like the thrust on a rotating shaft.
Combined load: Combination of radial and axial loads, common in many applications.
Other types of loads include moment load and dynamic load.
Hardness and toughness are important properties in materials science for determining resistance to deformation and ability to absorb energy.
Hardness refers to a material's ability to resist deformation, scratching, or indentation.
Toughness is the ability of a material to absorb energy and plastically deform without fracturing.
Hardness is often measured using the Mohs scale for minerals or the Rockwell scale for metals.

Bearing is a machine element that allows one part to bear another part's weight and facilitate relative motion between the two parts.
Bearing is used to support rotating shafts in machinery.
It reduces friction between moving parts.
Common types include ball bearings, roller bearings, and plain bearings.
Examples: wheel bearings in cars, bearings in electric motors.
The strongest bearings are typically made of materials like steel, ceramic, or titanium for high durability and load capacity.
Steel bearings are commonly used for their strength and durability.
Ceramic bearings are known for their high resistance to corrosion and wear.
Titanium bearings are lightweight yet strong, making them ideal for certain applications.
I was interviewed in Apr 2024.
