The O-ring is a manufacturing component that has been around for over a century. Thanks to their design simplicity and practical nature, O-rings remain in widespread use to this day. Their function is as simple as their design, which serves to create a tight, leak-proof seal between two components. They are very similar to gaskets, although O-rings are normally used in higher-pressure environments where other seals parts would fail. O-rings work by sitting between two other pieces that will be connected. The O-ring lies in the connective joint between the two parts where, once under pressure, will shift around causing it to more tightly hold onto the inner and outer walls of the pieces it’s connecting.

Bevel gears are gears where the axes of two shafts intersect, and the tooth-bearing faces of the gears themselves are conically shaped. Bevel gears are typically mounted on shafts that are 90 degrees apart but can be designed to function at other angles as well. One of the most common use of bevel gears is in the differential of a vehicle, where it transmits power generated by the power engine to the vehicle’s wheels.

To understand how an airplane’s wings keep it in the sky, we first have to understand the forces influencing all aircraft - thrust, drag, lift, and weight. Thrust is the force that propels the aircraft forward provided by its engines, both piston and jet turbine. Drag is the force trying to pull the aircraft back, generated as the aircraft displaces the air in front and around it. Lift is the force generated by the airplane’s wings and the flow of air over and below them, while finally weight is the force of the Earth’s gravity trying to pull the plane back to the ground.

Vehicles go, but how do they stop? What components are involved in bringing a moving object to a halt? The answer lies within the aircraft braking system, specifically, brake calipers. Brake calipers play a crucial role in allowing your vehicle to stop and contribute to the overall safety of its operation. Understanding how they function can be essential in comprehending how the differing systems of your car.
